Clearly motivated by his mistake that let West Brom get their consolation. He's a smart lad though and still young, I'm sure he'll learn from that and no doubt Bielsa will do his bit to ensure he does.
In the meantime am I the only one who thinks that with plenty of time to recover till pre-season starts, it may end up being a blessing in disguise? Not keen on the Euros going ahead as is given the current situations and he may well have picked up an even worse injury during the competition. Pure conjecture I know, but still.
