I wasn't advocating keeping him, just pointing out that if we'd have scored a few more, as we should have, his errors wouln't have been nearly quite so costly. He's also kept us in a few games too.
I really can't remember Mitchell making a save that I thought "Wow that was good", I will confess that I haven't watched all the away matches but all I can remember are routine saves or like against Ipswich where the guy hit it straight at him. I would be interested on which games you think "he's kept us in it"
