I’ve done mine twice and a Physio told me just that, that some people’s posture/biomechanics makes them prone to it. Obviously I’ve not received the rehab a professional athlete receives but it’s a fucker to recover from.Not sure if Essien's original injury was as bad as Mendy's? Essien had two ACL injuries and operations on his right knee 2008 & 2011 and one on his left in 2010. Perhaps he had an innate physical weakness.
That must have been a difficult few years for him.
