Is the Super-Sub a Real Player Type? What Substitute Data Shows About Impact From the Bench

A super-sub in football is a player, usually a forward, believed to have a special knack for changing matches after coming off the bench. Substitute data supports the impact-sub role as a squad function, but rarely proves an individual skill. Lineups and match timelines on RubiScore show when each substitute entered and what followed.

This data-study asks one question: is the super-sub a genuine player type, or a label created by the moments substitutes are given? It looks at what substitute data captures, what it shows, why it flatters bench players and how the idea could be tested fairly. Substitution times, scorelines and match events are available at https://rubiscore.com for checking the context behind any goal from the bench.

What Do Fans Mean by a Super-Sub?

The image is built on memorable moments. In the 1999 Champions League final at Camp Nou, Manchester United trailed Bayern Munich until stoppage time, when substitutes Teddy Sheringham and Ole Gunnar Solskjær both scored to win the match 2-1. Earlier that year, Solskjær came on in the 71st minute of an 8-1 win at Nottingham Forest and scored four times. According to Opta Analyst, he remains the only player to score four goals as a substitute in a Premier League match.

Behind the label sit three separate claims:

• The player produces more from the bench than as a starter, measured fairly per minute.
• The effect repeats across seasons, not just in one memorable spell.
• The effect belongs to the player, rather than to the situations in which he is used.

The first claim is easy to observe in raw numbers. The second and third are much harder to prove.

What the Data Captures

Basic substitute data comes from lineups and event records: the minute a player entered, the score at that moment, minutes played, shots, goals and assists. Event data adds expected goals (xG) for each shot, and tracking data adds running intensity.

Career totals are the most quoted figures. Opta Analyst lists Jermain Defoe as the Premier League's top-scoring substitute with 24 goals, each in a different match, followed by Olivier Giroud with 21, who made 103 of his 255 Premier League appearances from the bench. These are impressive tallies, but they mostly measure opportunity. A player who comes on often has more chances to score as a substitute, and a total says nothing about rate or context.

What the Data Shows

Three bodies of evidence are useful.

Substitutes run harder. A study of Premier League matches by Bradley, Lago-Peñas and Rey, published in 2014 in the International Journal of Sports Physiology and Performance, found that substitutes covered more high-intensity running than players who completed the match or the players they replaced. The difference was most visible in attackers. When the same players were compared, they ran more at high intensity as substitutes than in the equivalent second-half period of matches they played in full. Pass-completion rates did not differ.

Late minutes are high-scoring minutes. An analysis of the Premier League, Ligue 1, Serie A and La Liga across three seasons, published by Alberti and colleagues in 2013, found that the share of goals generally rose through the match, from 13.7% in the first 15 minutes to 20.2% in the last 15. The authors noted that fatigue alone could not explain the pattern, and pointed to the scoreline and the reduced time remaining.

Bench goals rose with five substitutes. Opta Analyst reported that in the first 30 Premier League seasons, substitutes' share of goals (excluding own goals) exceeded 12% only once, at 12.8% in 2013-14. After five substitutions arrived in 2022-23, it stayed above that level, peaking at 13.3% in 2023-24. Substitutes scored a then-record 132 goals in 2022-23, and 159 in 2023-24 set a new record. Opta Analyst attributed the rise to longer matches, the five-substitute rule and a higher overall scoring rate.

None of this shows that particular players are super-subs. It shows that the substitute's situation is favourable.

Why Bench Numbers Flatter Substitutes

Per-90 rates for substitutes are shaped by the conditions they play in. The main confounders are:

• Tired opponents. A fresh attacker entering after 70 minutes faces players who have already run for most of the match, and research has repeatedly found signs of fatigue towards the end of games.
• Game state. Managers tend to send on attackers when chasing a result, and the 2014 study found that substitutions became more attacking as each half progressed. Late minutes in a chasing situation are often open, with space at both ends.
• Selection effects. The player is chosen for the situation. A forward brought on when his team needs a goal is matched to the moments most likely to produce one, which inflates his rate compared with a starter who also plays through quiet spells.
• Added time. Stoppage time stretches the final phase of a match, and substitutes play a large share of their minutes in it. Whether a data provider counts those minutes changes the per-90 figure.
• Small samples. A substitute playing 20 minutes a match needs many appearances to reach a reliable sample. One goal in 150 minutes is a rate of 0.6 per 90, and one more goal doubles it.
• Starters having a good day. Big bench performances often come from regular starters. Opta Analyst noted that Son Heung-min was dropped for Tottenham's match against Leicester City in September 2022 after failing to score with his first 17 league shots of the season, then came on in the 59th minute and scored a hat-trick. That was a finishing drought ending, not a new player type appearing.

What Did the Five-Substitute Rule Change?

In May 2020, following a request from FIFA to protect player welfare during the pandemic, the International Football Association Board (IFAB) gave top competitions the temporary option of allowing five substitutes. The option was extended several times and made permanent at the IFAB's annual general meeting on 13 June 2022, taking effect in the Laws of the Game from 1 July 2022. Changes are still limited to three opportunities during play, plus half-time.

Adoption was left to competition organisers. The Premier League used five substitutes when the 2019-20 season resumed, returned to three for 2020-21 after clubs voted against keeping five, and agreed in March 2022 to allow five from 2022-23, with nine named substitutes.

For bench impact, the change matters in two ways. More substitute minutes mean more goals from the bench, which makes impact subs more visible and more valued. It also means more players spend part of their season as substitutes, so a team's bench goals increasingly reflect squad depth and rotation rather than one specialist.

How Could the Idea Be Tested Properly?

A fair test of an individual super-sub skill would compare like with like:

1. Same player, both roles. Compare a player's output as a substitute with his own output as a starter, not with the team average.
2. Comparable game states. Compare minutes played at similar scorelines and similar stages of the match, for example the final 25 minutes when level or one goal behind.
3. Minutes thresholds in each role. Set a meaningful minimum for both bench and starting minutes, so one hot spell cannot dominate.
4. Shots and xG rather than goals. Goals are rare and noisy. Shot volume and expected goals stabilise faster and show whether the player created more chances or simply converted a few.
5. Multi-season samples. Check whether a player's bench advantage in one season predicts the next. A real trait should repeat, while luck usually fades.
6. A substitute baseline. Compare against other substitutes in the same positions and situations, since all of them benefit from fresh legs and tired opponents.

On RubiScore, lineups record each substitution with its minute, and match timelines show the score at that moment and the events that followed, which is the raw material for the game-state and baseline steps.

A Hypothetical Example

Imagine a forward, Player X, who scores six goals in 600 minutes off the bench, a rate of 0.9 per 90, against 0.45 per 90 as a starter. The label writes itself.

Now add context. Four of the six goals came when his team was chasing the game, against opponents defending a lead. His xG per 90 off the bench is only slightly higher than as a starter, and most of the gap in goals comes from finishing above his chance quality. The following season, his bench rate falls back towards his starting rate. The evidence points to favourable situations and a hot finishing spell rather than a distinct super-sub ability.

Verdict

The impact-sub role is real. Substitutes run harder than the players around them, late minutes are rich in goals, and the five-substitute rule has made goals from the bench a larger share of the total. Squads that keep fast, direct attackers for the final half-hour are using a genuine squad function.

A stable individual super-sub skill is much harder to establish. Most of what makes bench numbers look special, including fresh legs, tired opponents, game state, selection and small samples, belongs to the situation rather than the player. The caveat is that some traits, such as acceleration against tiring defenders or the ability to adjust quickly to a match already in progress, may genuinely suit certain players to the role, and clubs with detailed tracking data may be able to detect them. From public data alone, the safest reading is that the super-sub is a role some players fill well, rather than a proven player type.
