Keepers are best judged when they are behind a settled defence and under sustained pressure, and in that scenario Foster was generally very good.
Sam came in behind an extremely dodgy back three and a system that was alien to all. I think that he has become more settled and confident under the present set-up, and is clearly playing to instructions with regards to playing out, and taking time.
In the early part of the season he was in my opinion, less culpable than the central defenders, in some shambolic performances.
He will be fine
