He is still only 22 but he still needs a couple more levels to become a 1st team regular. Fletcher has shown how much improvement can be made in a year so it is possible (there is 16 months between them in age) .Eagles has the talent to be a PL player no doubt but like Bentley at Blackburn he might have to move to fulfil potential.
I don't know why people say he was crap. He wasn't spectacular, but I thought he generally did his job quite well. Enough that I thought he might be able to push Park as our squad winger.
