A man has been charged after an alleged assault of Manchester City midfielder Jack Grealish at Old Trafford on Sunday.
The incident occurred at the end of City's Premier League clash with Manchester United, which ended in a 0-0 draw.
It is alleged that Grealish was slapped in the face by a man close to the Old Trafford tunnel as the two sets of players walked off the pitch after full-time.
City have declined to comment. United sources told ESPN that the club are cooperating with the investigation.
