Midfielder Adam Clayton has joined Championship newcomers Huddersfield Town for an undisclosed fee.

The 23-year-old was placed on the transfer list by United manager Neil Warnock at the end of last season after failing to agree a new contract with the club.

Clayton, who has signed a three-year deal with the League One Play-Off winners, made 50 appearances for United after initially joining on loan from Manchester City in the summer of 2010.

The United boss has already snapped up Derby midfielder Paul Green and is looking to strengthen his squad in the coming weeks for an assault on the Championship next term.
