The Blues lost their Brazilian midfielder in the 1st half of their 4-0 win due to muscle problems, and will also be without the Spanish attacker for Saturday’s London derby.

Chelsea’s opening Champions League fixture saw the London giants return to winning ways, but Wednesday’s victory came at a heavy price for the defending English Premier League champions.

Mourinho’s crew hosted Maccabi Tel Aviv at Stamford Bridge in search of a confidence-boosting victory, coming straight off a shock 3-1 loss to Everton, but achieved what they were in dire need of, winning 4-0.

However, the match-up claimed Brazilian midfielder Willian, who was taken off the pitch after 23 minutes due to muscle problem.

After the final whistle, manager Jose Mourinho revealed that the injury to the Selecao ace will rule him out of Saturday’s exciting London derby between the Blues and rivals Arsenal.

Another player unlikely to feature in the weekend heavyweight tie is summer signing Pedro. The Spaniard fell to injury in the trip to Goodison Park, and failed to recover in time for Wednesday’s Champions League outing, with little hopes of making Saturday’s match.

"Willian is out for sure, I think Pedro is out for sure. I prefer problems when players are playing well than problems when players are playing badly,” Mourinho stated.

The 4-0 win saw under-fire Spanish striker Diego Costa score his first official goal of the new season, however, the Special One held praise for youngster Ruben Loftus-Cheek, one of six changes made to Chelsea’s starting lineup.

"I think he [Loftus-Cheek] played very well which is very good for us," the Portuguese boss claimed.

"I think he is in conditions to compete with the others for positions and minutes but he is having minutes.

"He played already in the Premier League this season, now in the Champions league. He's potentially a very good player.

"You have to feed these young players and choose the right moment but the reality is that his evolution is important."
