“Mathieu struggled at left-back. The understanding between Jordi Alba and Jérémy Mathieu over the last few seasons has been sublime, combining well and covering for whoever was furthest forward. Mathieu appeared more vulnerable with a more natural winger in-front of him, Markel Susaeta and Óscar de Marcos both gave him a torrid time in the first half, crossing the ball early when he wasn’t tight enough, beating him individually and looking to overload him with 2 v 1situations. It was no surprise the opening goal came from his side as he was caught out positionally, as Iker Muniain’spass got in behind him, though the Frenchman was unfortunate that his last-gasp sliding challenge fell to Aritz Aduriz. Who opened out his body and executed a curling effort into the back of the net.” La Liga UK
