The Serbian midfielder admits to having been short of full fitness towards the end of last season, with an abdominal issue forcing him under the knife
Nemanja Matic admits that he was forced to play through the pain at Manchester United last season, with surgery required over the summer in order to get him back to full fitness.
The Serbia international made 49 appearances for the Red Devils in 2017-18 before then heading off to Russia on World Cup duty with his country.
He was feeling the strain by the time those commitments came to a close and eventually had to go under the knife after returning for pre-season training in America.
