The rise in anterior cruciate ligament injuries in the Premier League this season is linked to players competing in more games, says Pep Guardiola's trusted knee surgeon Dr Ramon Cugat.
This month, Manchester United defender Lisandro Martinez became the 10th top-flight player to injure his ACL this season.
That is the most there has been since 2016-17, when there were 12 in the whole season. There were nine during the 2023-24 campaign.
Dr Cugat, who has been treating Guardiola's players since the Manchester City manager's days in charge at Barcelona, told BBC Sport there is "no single cause, but rather a set of situations that increase the probability of injury".
