Diego Costa has two weeks to prove he can fire Chelsea back up the table, or they will move to sign a replacement.
The man they are rumoured to have targeted is Napoli's Gonzalo Higuain. Reports claim that Chelsea will bid for the Argentine if Costa's erratic form does not improve.
Higuain has already scored 13 goals for Napoli this season, taking his record for the club to 66 strikes in 119 games. Watch him in action below.
