Well I think Ayala will come back and challenge for a first team place he's only 21 and hasn't done much wrong in a Norwich shirt. Heard he's playing really well for Forest as well.
He's managed 8 games already this season, I might be wrong but he didn't play the first 4 or so league games, I don't know why, to be fair. Yeah he has a hamstring injury at the moment according to BBC, which will see him out for 3 weeks. I still rate him though, I think he is a good player. They did bring Ward in to cover Ayala, but I remember there were a few rumours that Forest wanted Ward in the summer. So probably helped it materialise quicker.
