I think that Coops definitely has a problem; if you look at his reputation over a long period with Plymouth, & his form in the first season with us, he is clearly struggling now in comparison. Whether that problem is physical or mental only the club knows.
The drop off is stark, he was imperious last season so it stands out a mile. As a former 'keeper I have been looking at his stance, & he seems to struggle low down near his feet (which lots of 'keepers also suffer with), & going high into the top corners of the goal, & I believe it is his knee or knee's that are the issue. He doesn't seem to have the same spring or be able to twist mid movement like he could.
I hope it can be sorted, at his best he is a hell of a 'keeper.
