38. Ron-Robert Zieler

Ron-Robert Zieler began his career with home-town club FC Cologne before joining United in the summer of 2005.

Good in one-on-one situations and an excellent shot-stopper, Zieler began life with United's U18s, playing 18 league games and four FA Youth Cup ties in his first season. His performances soon backed up his potential, earning a reserves call-up. He was an unused substitute in 11 second-string matches that year, including the 2006 final of the Manchester Senior Cup.

The following season Zieler shared U18 duties with Ben Amos, but also made his reserves debut in a 3-0 defeat to Sheffield

United. Four days later he kept a clean sheet in the Manchester Senior Cup against Oldham. In 2007/08 he and Tom Heaton vied for the reserves' no.1 spot.

That summer Ron-Robert started every game in Germany's triumph at the UEFA U19 Championships, playing a key role and continuing his rise through the international ranks.

At the start of the 2008/09 campaign, Zieler was given the no.38 shirt, and was named on the bench in the League Cup against Middlesbrough in September 2008. A loan spell at Northampton Town followed, where he made two appearances before returning to the Reds in February 2009.
