Last Sunday, Liverpool faced Manchester United within the English League Cup FA Cup quarter-final – and within the last minute of overtime, with the rating tied at three points, Liverpool had a key opportunity for a corner kick. A goal would definitely mean victory, but losing possession may very well be dangerous.
What was Liverpool alleged to do? Attack or play it protected? And in the event that they were to attack, what can be the most effective technique to accomplish that? What kind of pass and where should players wait to attack the ball?
Such decisions after set pieces are necessary not only in football, but in lots of other competitive sports, and are traditionally made by coaches based on long experience and analyses. But Liverpool recently turned to an unlikely source for advice: researchers at Google’s UK artificial intelligence (AI) lab. Deep Mind.
IN article published today in Nature Communications, researchers from DeepMind describe an artificial intelligence system for soccer tactics called TacticAI that would help develop effective corner kicking procedures. The article found that in 90% of cases, Liverpool experts preferred TacticAI’s advice to existing tactics.
What TacticAI can do
After a corner kick, play is stopped and each team has a probability to prepare their players on the pitch before the attacking team kicks the ball back into play – normally with a selected, pre-determined plan that can (hopefully) allow them to attain a goal. Advising on these pre-determined plans or procedures is what TacticAI has to supply.
The package consists of three elements: one which predicts which player is almost certainly to receive the ball in a given scenario, a second that predicts whether a shot will likely be taken on goal, and a 3rd that recommends methods to adjust players’ positioning to extend or enhance reduce the possibility of an accurate shot.

Trained on a dataset of seven,176 corner kicks from Premier League matches, TacticAI used a way called “geometric deep learning” to discover key strategic patterns.
The researchers say this approach may very well be applied not only to soccer, but to any sport by which a break in play allows teams to deliberately and non-contact position players and plan the subsequent sequence of play. In football, it may very well be expanded in the long run to incorporate throw-in procedures and other set pieces similar to attacking free kicks.
Huge amounts of knowledge
Artificial intelligence in football is nothing recent. For example, even in amateur and semi-professional soccer, AI-based auto-tracking camera systems are becoming commonplace. During the recent Men’s and Women’s World Cups in 2022 and 2023, artificial intelligence combined with advanced ball tracking technology enabled semi-automatic offside decisions to be made with unprecedented accuracy.
Professional football clubs have analytical departments using artificial intelligence at every level of the sport, mainly within the areas of: scouting, recruitment AND monitoring athletes. Other studies have also tried to do that predict players’ shots on goalor guess what from the movie what players do off-screen.
Incorporating artificial intelligence into tactical decisions can provide coaches with a more objective and analytical approach to the sport. Algorithms can crunch massive amounts of knowledge, identifying patterns that is probably not visible to the naked eye, giving teams useful insight into their very own and their opponents’ performance.
A useful gizmo
Artificial intelligence could be a great tool, nevertheless it cannot make gameplay decisions by itself. The algorithm can suggest the optimal position configuration for a corner attack or methods to best use the opponent’s defensive tactics.
AI cannot make decisions on the fly – for instance, deciding whether to quickly take a corner kick to benefit from an opponent’s lack of concentration.
It can also be price mentioning that players are allowed to be creative in some situations. When teams use AI to suggest the optimal strategy for corners, opponents will undoubtedly counter-attack using their very own AI-powered defensive setups.
While the technology behind TacticAI could be very interesting, it stays to be seen whether it’ll have the opportunity to evolve and be useful in open play. Can artificial intelligence get to the purpose where it may well recognize a player’s best tactical change in a given situation?
DeepMind researchers focused on the advanced decision-making process on this area future researchbut will he ever reach the purpose where coaches trust him?
From conversations with people within the industry, it seems that many individuals consider that artificial intelligence should only be used as an input to decision-making, and not allowed to make decisions by itself. Nothing can replace the experience and instinct of the most effective coaches, the elusive ability to sense the needs of the sport, change formations, and play with someone out of position.
Smart tactics – but what about strategy?
Coming back to Liverpool’s crucial corner in last Sunday’s FA Cup quarter-final: We do not know if Liverpool manager Jurgen Klopp took AI’s advice into consideration, but the choice was made to go for the corner, probably within the hope of scoring the last goal… a minute winner.
Crossing into the box might have been the tactic with the best probability of scoring, but every thing quickly went fallacious. Manchester United took the ball, moved it up the pitch in a counter-attack and scored the winning goal, knocking Liverpool out of the tournament on the last minute.
So, while the AI may suggest optimal play and positioning at a set piece, the coach may resolve it’s wiser to play it protected and avoid the chance of counter-attacks. If TacticAI continues his profession as an assistant coach, he’ll little question learn that keeping the ball within the corner and taking penalties can sometimes be a greater option.
