“This charge relates to an incident which took place at Old Trafford Football Club yesterday.”
Grealish is likely to leave this summer with several sides looking to snap him up, including rivals Tottenham who may seek to replace Heung-min Son who has just one year left on his contract. The former Aston Villa man could depart along with Ilkay Gundogan and Kevin De Bruyne at the end of the season as manager Pep Guardiola looks to refresh his side.
