Chelsea manager Jose Mourinho has revealed that striker Diego Costa will start against Arsenal on Sunday, despite concerns regarding his hamstring.

The Spaniard has been struggling to train between matches but Mourinho will include the 25-year-old, who has netted eight goals in as many games since he joined the club from Atletico Madrid.

Midfielder Cesc Fabregas will also feature against his former club, while Cesar Azpilicueta and Willian are likely to return after being dropped to the substitutes' bench for the triumph at Sporting Lisbon.

Arsenal boss Arsene Wenger hasn't defeated Mourinho in 11 games, but his team will arrive at Stamford Bridge after thrashing Galatasaray in the Champions League.

Striker Danny Welbeck recorded a hat-trick on Wednesday night in an attack-minded team but Wenger could opt to change things in the middle of the park for the trip to West London.

Jack Wilshere will return to partner Mathieu Flamini, while Tomas Rosicky could also come into contention.

Wenger has dismissed injury concerns surrounding Alexis Sanchez after the winger was seen with an ice-pack on his foot.
