"Diego is a good keeper," he told liverpoolfc.tv. "Technically, he is almost perfect, and he is quite complete.
"It is important for him to come in and do well and to keep a level high because if he does that it can only be good for the squad.
"It is always positive to have competition for places and it is no different for me.
"Hopefully, Diego will continue to play well and that will make me play well also because that will be good for the team."
