30. Lee Martin

Lightning fast, driven and full of boundless energy, Martin is a nightmare for opposition defenders.

Coveted by many Premier League clubs, Lee signed for United in December 2003. His first full season at Old Trafford brought six reserve-team goals as he was quickly fast-tracked from the Under-18s.

An integral part of Ricky Sbragia's Quadruple-winning side in 2004/05, Martin's fine form continued into the 2005/06 season and he made his first-team debut in the League Cup win over Barnet in October 2005.

In January 2006, Lee was one of five United youngsters sent

out on loan to Royal Antwerp, where he quickly caught the eye with his energetic performances.

Although the Belgians’ bid for promotion ultimately failed, it wasn’t for lack of trying on the young winger’s part, and he was named the fans' Player of the Season for his efforts.

Sadly he was unable to have a similar impact in his next loan move, at Scottish giants Rangers. The Ibrox side's poor form, together with a niggling knee injury, prevented Lee making his mark on the SPL.

Upon returning to England, Lee attracted the interest of a host of clubs, with Championship side Stoke taking him on loan until the end of the 2006/07 season.

Martin turned in consistently fine form with the Potters, although Tony Pulis' side ultimately failed to reach the playoffs. Buoyed by the experience, Lee returned to Carrington a far more experienced player.

He toured the Far East with United in July 2007, scoring against Chinese side Guangzhou Pharmaceutical, and earned another first-team chance in the Carling Cup defeat to Coventry City two months later.

Further loan spells at Plymouth Argyle and Sheffield United followed, although

the latter was cut short by a knee injury.

Martin again went on United's pre-season tour of South Africa in the summer of 2008 and scored the winner against Orlando Pirates in the Vodacom Challenge.

The midfielder spent the first half of the 2008/09 season on loan at Nottingham Forest, where he scored one goal in 14 appearances.
