He also played in the Football League for Cambridge United, Brentford and Wolverhampton Wanderers before finishing his career in non-league with Burton Albion, Bromsgrove Rovers and Fleet Town.

He is the youngest player to play a league game for Cambridge, and is one of only two product of the club's youth team to become a full England international:[3] John Ruddy of Norwich City followed Sinton to this accolade in 2012.

Sinton played for QPR in the first year of the Premiership, where he scored a hat-trick in a 4–2 win against Everton on 28 December 1992,[5] before moving to Sheffield Wednesday for a then club record £2.75million in August 1993.

On the international front, Sinton made his England debut in a 1–1 draw in Poland in November 1991 and went on to acquire 12 caps – including two against Sweden during a disappointing European Championships campaign.

[8] He played David Platt through on goal for England's penalty claim that was turned down, and absolutely should have been given, in their 2–0 defeat against the Netherlands in Rotterdam in October 1993, towards the end of Graham Taylor's reign.

[1][8] Sinton was appointed manager of Isthmian League Division One outfit Fleet Town in summer 2005, having spent the previous season as the club's Football Development Officer.
