Chelsea boss Mauricio Pochettino has refused to blame the medical staff for the ongoing injury crisis rampaging the club.
Chelsea had 12 players out injured for the goalless draw against Bournemouth last weekend.
“Before we arrived here we did everything to try and have a clear idea of why there were too many injuries last season also, to analyse the risk,” said Pochettino.
“It’s (about) the profile of the player, the risk of the player. It’s not the people working in the medical staff of performance area.
“I think we need to respect these areas (at the club) are very good professionals, qualified people. That’s why they are working in football. But there’s an individual risk to (certain) players, you need to assess.”
Pochettino added: “Then there’s bad luck. We have injures that maybe happen in one season or maybe in two, but have happened (to Chelsea) because of different situations you cannot control.
“Christopher [Nkunku] against Dortmund, it was a tackle and he twists his knee. Three or four months out. That is from the beginning of the game, he wasn’t tired, he was fresh, good, strong.
“The organisation in football are super professional and we need to respect that. Sometimes things happen like this and it’s difficult to evaluate.”
