We've been watching so many games with Wout on those. There's a pattern. Wout started as main striker, with Rashford on the wing. Then as game went on, it's either Wout came off or he dropped deep into 10, where Rashford became the striker. This happens so many times, any United fans should've seen it.
My take on this. EtH mentioned before that he likes opponents to get use to defending on certain type of play, then he changes the attackers to make opponents need to change their mindset. He has Wout as battering ram who just press like maniac, then on 3/4th of the game, has a speedy Rashford who eats through ball (playing on the defender shoulder).
So the talk that Elanga or Bruno could do what Wout can is a disservice to the big man. We battered Barcelona on their own turf playing this tactic.
But it's all probably just BS, and Wout is just EtH's lovechild, like some mentioned.
