He was injured while with PSV, and was not able to play consistently during his second season with the team. He then signed with Chelsea, where he played well, but spent most of his time recovering from a series of severe injuries. He then spent one year with Real Madrid, and was then sent to Bayern Munich. He started slowly with Bayern, but has since proven himself. In mid-May 2014, he became the first player to score in three separate DFB-Pokal finals.
