Quite astonished some think he can play wide. He can't beat a man and isn't the quickest. He either plays at 10 or he learns to properly position himself as an 8.
I don't see him as a wide man, he doesn't have any ball carrying abilities, if you look at the way ETH uses his number 10 in a 4231 Bruno would excel playing that role.
In the build up play his team usually form a 3151, one of the CM dropping deep to form a back three the other staying in front of the back three allowing the number fullbacks to push higher, both wingers move slightly inward with and the center.
So basically the front four forms a narrow diamond, pinning the opponent back four and at least one midfielder back, that's already 5 of their outfielders who have to maintain deep position, there will always the one free man at among the deeper players unless the opponent is willing to play 4vs4 against the forward players.
The back three spreads across, made of one midfielder and the two center spread across the back line giving both wider players and angle to progress the ball, with the option of playing into the the fullback out wide or to the feet of one of the front four dropping off or into a channel ball down the flank.
So expect to see variation in movement from the front four, center forward drops off to receive to feet. No10 runs behind to make the space for him, same kind of movement from the wingers. All coached to a high degree.
