Chelsea striker Diego Costa went to hospital with the rib problem he sustained in the Capital One Cup loss at Stoke, Jose Mourinho has said.
Costa came off clutching his side in the 33rd minute of the fourth-round tie at the Britannia Stadium, which the Blues lost 5-4 on penalties following a 1-1 draw after extra time.
Asked in his post-match press conference what the situation was with Costa, Mourinho replied: “He is in the hospital – I don’t know.”
When then asked if the Spain international would be a doubt for Saturday’s Barclays Premier League home clash with Liverpool, Mourinho said again: “I don’t know.”
Costa was substituted shortly after being sandwiched between Ryan Shawcross and Charlie Adam in a tackle and then trying to muscle his way towards a Willian cross that Stoke goalkeeper Jack Butland punched away.
And Mourinho added when asked how the injury had happened: “I think he punched himself.”
