The 2012–13 Borussia Dortmund season started on 18 August 2012 with a win against FC Oberneuland. Borussia Dortmund qualified for the 2012–13 UEFA Champions League and were scheduled against Ajax, Manchester City and Real Madrid. The club's opening league match was against Werder Bremen on 25 August and their opening Champions League match was against Ajax on 18 September. Hamburger SV end the club's 31-match unbeaten streak on 22 September. On 30 April, Borussia Dortmund qualified for the 2013 UEFA Champions League Final. However, Real Madrid manager José Mourinho was critical of referee Howard Webb of not giving Mats Hummels a red card after handling the ball. Cristiano Ronaldo would have had a breakaway if not for the handball. Mourinho claimed that Webb spared Hummels for the Champions League Final.
