Im sorry you are out of your mind if you think2 years ago he was a good keeper. 2 years ago he was the 2nd worst keeper in the Premier League, only because a keeper named 'Tim Howard' was unfortunately playing for us.
He was very very good at Stoke. He had an iffy few months followed by and injury, during which he was replaced by Butland. He was then sold to Chelsea.
I'm not out of my mind at all. I know exactly what I'm talking about in this case... Maybe he wasn't at his very best in 14/15, but he was superb for the previous two seasons before that. If he gets back to that form it'd be a very smart buy.
