Be interesting to see what happens with Rashford if Ole is looking to use Pogba there more often.
I do like Pogba in that role, though. As others have mentioned, effectively, it gives us that extra body in midfield, thus being able to control games a bit more.
It's similar to how Pogba played when at Juventus.
I personally think if we are going to play like that going forward, then we don't really need to buy a right-winger. With Greenwood and Rashford as the wide forward options, I'd focus on bringing in a controlling centre midfielder and a dominant centre back.
