Yeah. They're effective because they often bring their wide men in late and from the centre, giving them options on both sides. But the wide men are also providing a lot of lateral movement, shifting defenders around and creating open channels for runners to slot into for high percentage shots near the goals.
This is what I would like to see Arteta get time to work on. If we are out of Europe, he gets the time to work on that daily and perfect it. If we are in, he gets to buy better players. That's the tradeoff. 🙂
