JOSE MOURINHO is determined to bring Atletico Madrid hitman Diego Costa to Chelsea this summer.
Costa is Mourinho's top transfer target, after identifying the 25-year-old as the ideal striker to lead the Blues' attack.
And Chelsea's bid to land Costa will be boosted by the Brazil-born star sharing an agent with Mourinho.
Jorge Mendes represents both Costa and Mourinho, with the 'super-agent' brokering a number of deals between Chelsea and Atletico.
According to reports, the Blues have already opened preliminary talks with Atletico over the 23-goal marksman.
Arsenal, Liverpool and Manchester United are also interested in Costa, but Chelsea are firm favourites and could tempt the Spanish side into a deal by including on-loan goalkeeper Thibaut Courtois.
Costa has a £32m release clause in his contract, but he has committed himself to Atletico for the rest of the season.
