Manchester United’s Nemanja Matic will miss the start of the new season after having surgery on an abdominal injury.
The midfielder has not featured in any pre-season games, including Saturday’s 4-1 friendly defeat to Liverpool.
“Matic came from the World Cup with an injury and the time he had to rest on holiday was not enough to resolve the problem,” manager Jose Mourinho said.
“He went to Philadelphia for a top specialist and he didn’t leave the clinic. He immediately had surgery.”
The Serb has returned to Manchester to continue his rehabilitation.
