I've watched Aurier regularly and for £7M he's an absolute bargain. He's a potent attacking threat from the wing. He loves to cross he love to be incisive in the final third but more importantly from what I've seen he's an intelligent full back.
He reads the game slightly above average than other players in Ligue 1 and he takes advantage. He knows when to defend and stay back or to run up the line and overlap. This has annoyed Toulouse fans a little because they're want constant attacking football but in reality they don't see the value of what he does.
He's a total athlete, strong, fast, bags of energy and stamina with a technique to deliver accurate crosses. He versatility is a key aspect also, he can play anywhere across the front 3, he becomes our 4th CB.
Obviously his stats are slight skewed because of the inferiority of Ligue 1. He's too comfortable in that league imo, he's allowed too much freedom down the right by opposition and so he has a big impact on games.
He has a bit of a discipline problem. He get over hyper on the pitch which lead to him remonstrating with refs alot. That needs to be coached out of him immediately or else he'll struggle in the CL and Prem.
Alain Casanova speaks highly of him, Aurier come across a professional although his public display of affection for Arsenal is quite bad. For Gooners we love it but it doesn't give of the best image to the people around him.
He a quality player, the ideal replacement for Sagna but I would not feel totally comfortable with just Jenks and him alone for RB. They're both still young and I think the pressure for playing for Arsenal will get to them and lead to mistakes as we've seen with Jenks.
Aurier potential link up with Theo is another thing that worries me, He performs much better when they're are technically based players on the wings.
