Jose to decide on Costa’s fitness.

Jose Mourinho says he make a decision on Diego Costa tomorrow
ahead of his side's clash with Arsenal.
Costa will be available for his side's Premier League clash on
Wednesday, even if he is not fit on Sunday.
The Chelsea boss revealed Didier Drogba is fit but Loic Remy
remains a doubt, and said everyone else is fit for the Premier
League title clash.
Dominic Solanke did not play for the Under-21s yesterday and
Mourinho added he will be called upon if needed.
Cesc Fabregas returns to face his former side on Sunday. His
manager is not expecting there to be any problems, and has no
worries about his midfielder dealing with a possible bad reception.
Mourinho is not focussing upon his impressive record against
Arsene Wenger and says it will be an achievement to win at the
Emirates.
He hailed the strength of Arsenal's squad but is confident his team will do enough to win.
The 52-year-old was adamant the Blues have not won anything yet and knows every club has pushed Chelsea hard in recent weeks.
Mourinho said: "Good projects end with titles. Cesc was looking for that."
