Former Premier League ref Mark Clattenburg has joined the staff at Nottingham Forest.

Forest have hired him to help the club understand referee rulings.

This season, Forest have lodged three appeals against decisions who have gone against them in Premier League matches.

The club are said to be unhappy with the number of rulings from both referees and VAR.

Clattenburg has joined Forest as a 'referee analyst'. He was at the City Ground for yesterday's win against West Ham.
