Manchester United's reserve goalie Ron-Robert Zieler has reached an agreement with Hannover over a summer move, the Bundesliga club announced. The 21-year-old, who joined United's youth ranks in 2005 from Cologne, has completed a trial at AWD Arena this month. Now he's poised to sign a two-year contract with Hannover, who are struggling to move clear of the Bundesliga relegation zone. German keeper Zieler will be deputizing for Hannover's first-choice goalie Florian Fromlowitz.
