There is something I dislike how his body positioning. He looks quite rigid. He doesn't shift his body weight quickly enough. I like agile midfielders.
In his compilations he's more often than not got a lot of time, with nobody closing him down. He opens up his body and it's painfully obviously when he's going to launch a cross field high ball. Will that get snuffed out by defenders in the PL? Possibly. It's possible that he'll attempt these super passes in this league only for defenders to react quicker, close him down faster and be there to intercept or block him.
Or the defenders positioned in the area's where the balls are being launch to, just head it away.
Good to notice these things, I am sure the Arsenal scouts are well equipped to make a better decision that any of us are, endless amounts of analysing etc. Just what I noticed.
I love some of his 20 yard smashes.
