Pedro, Willian out of Arsenal clash, confirms Jose Mourinho

London: Chelsea will be without Pedro and Willian in Saturday`s Premier League clash with Arsenal, manager Jose Mourinho has said.

Mourinho`s team have made a stuttering start to their Premier League title defence, managing four points from their five games that leave them fourth from bottom in the league table.

Opponents Arsenal have recovered from their opening day shock defeat to West Ham United to collect 10 points from five games and sit fourth in the table.

Willian, who scored the opener in Chelsea`s 4-0 Champions League win against Israeli side Maccabi Tel Aviv on Wednesday, was forced off in the 23rd minute and Pedro didn`t feature in the win.

"Tomorrow I will watch Arsenal, and I will try to understand how my players are -- how Oscar is, Willian is out for sure, I think Pedro is out for sure -- so let`s see," Mourinho told reporters.

Pedro and Willian have contributed four of the seven league goals Chelsea have scored and they will be sorely missed as the Blues prepare to take on an Arsenal side who have kept three successive clean sheets in the league.
