Injuries and inconsistent form meant Haller's role in the Champions League final a year later was as a late substitute when Dortmundlost 2-0 to Real Madrid. It was to be his last game for Dortmund before loans last season with Leganes in Spain and then Utrecht. Haller returns on a one-season contract to familiar surroundings at Utrecht, where his prolific scoring a decade ago helped to launch his career.
