Manchester City midfielder Kevin De Bruyne is reportedly set to be out for four weeks with the hamstring injury he sustained in Saturday's victory over Swansea City.
That would mean De Bruyne would miss the Champions League game against Celtic on Wednesday as well as Premier League games against Tottenham and Everton, while he would be a major doubt for the trip to Barcelona on Oct. 19.
He would also miss Belgium's World Cup qualifiers against Bosnia-Herzegovina and Gibraltar on Oct. 7 and 10.
However, the Press Association subsequently reported that City do not expect to have a full prognosis of De Bruyne's injury until Tuesday.
Speaking after Saturday's game, City boss Pep Guardiola had said: "I think he's injured.
"Tonight we are going to come back to Manchester, tomorrow the doctor is going to see. It's a pity. It's important for us. For how he reacted it looks muscular but I'm not a doctor."
