Manchester City midfielder Kevin de Bruyne could face a spell on the sidelines after injuring his right knee in training, the Premier League champions said Wednesday.

The 27-year-old, who enjoyed a superb World Cup as Belgium reached the semi-finals, is undergoing tests to assess the seriousness of the injury.

"Kevin De Bruyne is undergoing tests on his right knee after sustaining an injury at training on Wednesday," read a club statement on its website.

"The extent of the problem is not yet known and we will bring you further updates on Kevin's condition in due course."

De Bruyne, who has been at City since 2015, scored eight goals and provided 16 assists last season in a series of dynamic performances for the champions.
