Chelsea striker, Diego Costa could miss clash with Crystal Palace

According to SportsMail, Chelsea striker Diego Costa is a doubt for the Blues' clash against Crystal Palace on Saturday through injury.

The Spain international, the current Premier League top scorer with nine goals, played in his nation's defeat to Slovakia and victory over Luxembourg during the international break.

Costa has returned from international duty with yet another problem with a suspected hamstring injury and has been having treatment this week.

Costa played all but eight minutes for the national team last week and Mourinho revealed: 'Yes. The Spanish team played in Luxembourg on Sunday. I gave them Diego, Fabregas and Azpilicueta.

'I gave them two days off, Monday and Tuesday, so they had to report to train on Wednesday at 3pm. And Diego was here Monday at 9am. So you can imagine how strong he was to be here at 9am on Monday.'

The Chelsea boss added: ‘I don’t lose my time contacting managers from national teams. In the past they used to contact me, but it is never my initiative to contact national team coaches.

‘They have the power, we don’t have the power.

'Every Chelsea player who is selected at that time, we are happy that the players represent their country.'

Mourinho would not confirm whether Costa had returned to the club on Monday in order to receive treatment.

Ramires, Andre Schurrle, John Obi Mikel and Didier Drogba could also miss the trip to Selhurst Park as Mourinho admitted Chelsea have a 'long, long' injury list.
