His decision making is suspect. Dives in for tackles when he should stay on his feet, shoots when passing would be the better option, tries to take a man on when there is no space etc.These are things that can improve with coaching and experience so I wouldn't write him off just yet.
When fist in the side he played to his main strength which was crossing the ball at ever opportunity. He put defenders on the back foot because the ball came in fast when their defence hadn't set up. Unfortunately it his one major asset, he doesnt have the pace of Gabby, he doesnt have the trickery to beat a full back, when posters started bigging him up i couldn't see what they were seeing. Gabby is still the best player to come through and over how long has that been? and i am in the minority i know in saying that Bannon has still to prove that he can become a valuable player for us. I think we have so little quality in the side that we see more than is there. Davis is a prime example, player of the year wasn't he? a young kid that we all wanted to succeed but was never good enough.
I think he's a very good player and hopefully he'll come good under AM. Not sure the way we play currently suits him though. He's also been found out to an extent - he's no longer a surprise, but thats normal. Good players will eventually adapt and i'm sure he will
