Chelsea manager Mauricio Pochettino has defended the club's medical team amid a lengthy injury list at the club.
The Blues were without 12 senior squad players for the goalless draw with Bournemouth last time out.
Some of them could return when Chelsea host Aston Villa on Sunday but a number of key players remain sidelined.

"I think we need to respect these areas [at the club] are very good professionals, qualified people.
