True, but just him alone will make a big difference i think. I saw some analysis on TV that was pretty interesting. Our midfield this season, and especially when McTomminay was injured never tried to vary their passing. Any and all threat from midfield came from Fred and at times Matic, and most of the time they tried a low pass into Martial/Rashford. Problem was that they took about 2-3 seconds to long every time, which meant the opponent could reorganize
This was made even worse after Rashford injury and as a result we became incredibly predictable and easy to defend against. Watch Martial closely and intercept the passes going to him and our only choice left is hitting it wide. No passes behind the defense means the other team also can push up pretty high with little risk and press us in midfield
Introduce Bruno. Not only does he move a lot, creating space for himself and others, but more importantly he has a great range of passing and is not afraid to hit some high risk passes behind the opponents. That makes us so much more unpredictable and much harder to defend against.
Its no coincidence that our best form under Ole (caretaker) came when Pogba was in brilliant form
