I'm not in favour of him signing either. But...McCarthy know him, and he is good running with the ball and creating things. He could play off the bench or in the middle with two from Bacuna, Ralls, Vaulks or Pack. We do need an extra body or two at the moment.
Having said that he is always injured and inconsistent when he plays, so he should fit in here fine! But surely there must be a promising 22/23 year old somewhere we could pick up for the same money. We'll be signing Adam Matthews, Tom Lockyer or Deji Oshilaja next.
