Wing play is actually so important, I think the lack of true penetration and presence out wide is another reason why our teams under Wenger served up the cancerball.
Too many #10s shoved out wide trying to the #10 role there just served up endless sideways passes in front of defences, who never looked like being stretched by a proper winger and we’re happy enough to let our bunch of shysters pass around in front of them all day.
You look at ALL successful teams these days, and they place huge emphasis on wing play.
The team that put in by far the most crosses into the box (low or high) are reigning 3 in a row European champions Real Madrid.
Crosses from the likes of Marcelo, Carvajal, Isco and Ronaldo are crucial to how they break teams down and they certainly wouldn’t have won three CLs in a row without this wing play.
Look at Man City, with Sane, Sterling and KdB putting in crosses and stretching teams out wide, Liverpool with Salah, Mane and Robertson, Roma using Perotti to pump balls in for Dzeko, France at the world cup with Mbappe, etc etc.
Good wing play is essential in this new era, as we move past tiki taka football. Whether that’s through great attacking full backs that cross the ball perfectly (low or high - I’d love to see our team use more pinpoint low crosses, they can be quite a potent attacking weapon) or fantastic dribbling wingers, it needs to be employed if Arsenal are to improve and do anything in future.
