Chelsea are planning to go head-to-head with Arsenal to sign Atletico Madrid striker Diego Costa, according to the Daily Star.
The 25-year-old hitman has been heavily linked with a move to the Emirates Stadium over the last couple of months as Arsene Wenger is keen to add a world-class striker to his ranks.
Arsenal were said to be preparing a £32million bid for the prolific striker but suffered a setback when Atletico stated that both Costa and Koke were not going to leave the Vicente Calderon Stadium in January.
And Arsenal's chances of signing Costa have hit another snag as Chelsea have now entered the race to sign the Brazilian forward in the summer.
It was originally thought that Jose Mourinho was keen on signing a striker during the January transfer window, however he stated last week that he is prepared to wait until the end of the season to land a striker of Costa's calibre.
Costa, who has a buy-out clause of £32million, has scored 19 goals in 19 La Liga games so far this season.
