Real allowed Ozil to leave for Arsenal after splashing out a world record £85million on Tottenham's Gareth Bale. And Ancelotti has conceded that the Spanish giants should not have allowed the German playmaker to quit the Bernabeu. "I think we made a mistake when we gave him the possibility to leave the club," said Ancelotti. "However, we have fantastic strikers and don’t need a back-up after Higuain’s departure." Real are third in La Liga behind joint-leaders Barcelona and Atletico Madrid.
