Chelsea working to understand reasons for injury situation – Mauricio Pochettino

Defenders Thiago Silva and Axel Disasi are the latest additions to the list since Saturday's 2-2 draw with Aston Villa, in which Pochettino was forced to name five academy graduates aged 20 and under on the bench. Notable absentees have included £70million defender Wesley Fofana, who has not played all season after undergoing surgery on an ACL injury, and forward Christopher Nkunku, a £52m summer signing who has been limited to seven Premier League appearances and who, despite returning to full training, will not be fit to face Spurs. Romeo Lavia, bought for £58m from Southampton, has played only once for the club while Reece James and Ben Chilwell have also had lengthy spells out of the side.
