Portsmouth manager Avram Grant has been charged with improper conduct by the Football Association after squaring up to a referee during a Premier League match on Tuesday night.

Infuriated by several decisions by ref Kevin Friend, the Israeli stormed on to the pitch at half time in the match against Sunderland.

Grant saw his team denied two penalty claims and have a player sent off. He was forced to watch the second half from the stands.

He has until next Thursday to respond to the charge, which will be heard by 5 March.
