Having only watched him at the start of last season until Koeman left, and this season he doesn't look anything out of the ordinary really. I don't see it.
However I don't think he is a major priority right now, but we should definitely have better than Stek as back up pushing to start ahead of him. It's the easy answer to any issues we might have with him.
Standards, basic standards. Decent backup in all positions.
Probably leads to the thinking that despite all the changes in the summer there is still a huuuge amount of work to do to get to that point. We barely have a decent full first XI.
