Atletico Madrid striker Diego Costa rejected offers from Manchester United, Manchester City and Arsenal due to his reluctance to break an agreement with Chelsea boss Jose Mourinho. The Brazil-born Spain international had given his word to sign for the Blues this summer.
This is information provided by Sunday Times' journalist Duncan Castles, who wrote a detailed article on Chelsea's pursuit of Costa for ONE World Sports. Chelsea are confident the 25-year-old, who scored 36 goals in 54 appearances for La Liga champions Atletico during the 2013/14 campaign, will adapt quickly with as many as three of his current teammates set to follow him to Stamford Bridge this summer.
Mourinho is also keen to complete deals for Brazilian left-back Filipe Luis and Portuguese midfielder Tiago Mendes, while goalkeeper Thibaut Courtois returns to the west London outfit after spending the past three seasons on loan at the Vicente Calderon.
Costa has been identified by Mourinho as the man to fire Chelsea to silverware next season. Over the past 12 months the Blues' boss has often complained that his team lacks a proper goalscorer, despite having the likes of Fernando Torres, Samuel Eto'o and Demba Ba all in his ranks. Belgium international Romelu Lukaku, meanwhile, was sent to Everton on loan for the season.
As well as £32 million Costa, Chelsea are also poised to complete the signing of fellow Spain international Cesc Fabregas, who was also linked with United, City and Arsenal. Barcelona are keen to receive a transfer fee of around £30 million for the World Cup winner.
