Chelsea target man Diego Costa has injured himself while on national team duty for Spain in this week's friendly defeat against France in Paris.
This was on back of strong rumors last week that the former Atletico Madrid player had an injury before Chelsea's clash with Everton at Goodison Park. But he silenced his doubters by scoring a scintillating hattrick in a 9 goal thriller.
The striker has injured his thigh as a statement from the Spanish FA read,
"Diego Costa has a myofascial injury to his hamstring muscle in his left thigh. The injury was detected with an MRI scan after the player expressed some discomfort during yesterday's match against France.
"All the tests carried out by the medical staff will be sent to Chelsea."
The 25 year old has returned to London with his club. He will be replaced by Barcelona's teen sensation Munir El Haddadi in Spain's Euros 2016 qualifier against Macedonia
