Cape Town - According to Sky Sports, Chelsea have agreed a £32m deal with Atletico Madrid for striker Diego Costa. Costa, who has played a starring role in the Spanish club's run towards a possible La Liga/Champions League double, has long been linked with a move to London, with Jose Mourinho desperate to sign a prolific striker. Chelsea have had a mediocre season by their own standards, and Mourinho suggested at the end of the final Premier League game of the season that he was keen to make his biggest splash into the summer transfer market as soon as possible. Chelsea finished the 2013/14 season in third place, four points behind Manchester City and two behind Liverpool, with their goalscoring record seen by many as the reason for them failing to win a trophy.The Blues scored 71 goals, compared to 102 for City and Liverpool's 101, and their only player in double figures was attacking midfielder Eden Hazard, who managed 14. Samuel Eto'o, Fernando Torres and Demba Ba scored only 19 goals between them, often leading to speculation Mourinho would make a big-money move for a player like Costa, who has scored 27 times in 33 appearances in La Liga this season. The deal with Costa is not expected to be formally announced until early June.
