Barcelona's Hansi Flick feels the refereeing was somewhat biased against Barcelona during the match against Inter Milan. However, were the manager's tactics what ultimately failed Barca in the Champions League tie? Poppy Miller, Nico Cantor, Nigel Reo-Coker, and Mike Grella suggest that the manager should look inward to assess where he is at fault. There's not much time for Barcelona to mourn their Champions League exit either, as El Clásico against Real Madrid is the next fixture for Barca.
