The Davies situation is a strange one.
It appears that Silva has reservations about him as he has had only a tiny part to play so far this season, but then last year he was made captain a couple of times.
It could be that the manager thinks Davies doesn't fit the system he wants to play... but then I would say there are some players getting regular games who do not seem to fit the system either.
On a side note, I was looking at the face of Gylfi Sigurdsson on the bench after he was taken off and to say it was stony would be a huge understatement.
I thought he looked angry, but that may just be me. I cannot help but feel that he thinks the team is not set up to best utilise his talents. How many shots on goal has he had this season ? If you take the goals away from his game then you are taking an awful lot of his game away.
