Ray Parlour has revealed Arsenal players were forced to have their wisdom teeth removed during Arsene Wenger's time in charge.
Wenger, who was Arsenal's manager between 1996 and 2018, transformed English football by introducing new training methods, diets, tactics and overseas stars. The revolution brought success, as Wenger's side won 17 trophies - including three Premier League titles.
Perhaps his most intriguing idea was removing wisdom teeth. According to Parlour, Wenger made the midfielder and other players do this because the teeth would cause "bad blood" to enter the body when they were pushing through, which led to fitness issues.
