He's a good keeper. Having a shaky unpredictable defence in front of him has hurt his confidence. He needs to toughen up and start barking out orders.
But he is still heaps better than Reina. Reina is fat and has no athleticism. Also Reina loses concentration frequently.
Reina has no athletism? I don't think you know what you are talking about, he had a bad spell which came with a few injuries, but he was already playing well in the 2nd part of last season and is doing well at Napoli according to Rafa (I haven't watched Napoli games so won't comment, just go by Rafa's word). However, that's not the point, I don't think that Mignolet should be transfered etc.
