Aspas hasn't impressed, no denying that, but he has been playing out of position, and was really playing shite in the last two games when most everybody were having mares. In a fully fit and firing team against Stoke and Villa, he had a decent outing. And while he didn't contribute much offensively against the Mancs, he did a job marking Carrick out of the game.
No excuses for his lack of trying when he came on against Swansea though.
