Costa set to miss Champions League final

But in good news for Atletico, midfielder Arda Turan could still prove his fitness ahead of the Champions League decider against Real Madrid on May 24.

Costa and Turan both limped off in the opening 25 minutes of Atletico's title-clinching 1-1 draw at Barcelona in La Liga on Saturday, with the former spotted in tears on the bench following a reoccurrence of a hamstring injury.

Spanish newspaper AS quoted Cerezo as saying Costa will be out for 'at least two weeks', which also casts doubt on the striker's hopes of being fit for the World Cup.

Turan came off seven minutes later following a collision with Barcelona midfielder Cesc Fabregas but reports throughout the Spanish media indicate he will only be sidelined for up to three days, which should give him a chance to make Diego Simeone's squad for the trip to Lisbon.
