Pepe Reina says he needs to up his game. Reina wasn't happy with his own performance against West Ham on Sunday and has vowed to improve. "Keeping those clean sheets was about not making mistakes, first of all. I did a couple of them on Sunday and I felt really disappointed with my performance individually," said the keeper. "I won't hide behind any teammates - I was poor and I have to recognise this and keep learning from the mistakes."
