Kroos was an important member of Bayern's treble-winning team during the 2012–13 season. As the most advanced member of a midfield containing Schweinsteiger and Javi Martínez, Kroos scored three goals in the team's opening four Bundesliga matches. He also scored his first Champions League goal in Bayern's opening group match against Valencia. After sustaining an injury in the first leg of the Champions League quarter-final against Juventus, Kroos was unavailable for the remainder of the season, missing Bayern's successes in the 2013 UEFA Champions League Final, the 2013 DFB-Pokal Final and the last seven matches of the Bundesliga season.
