Welcome to Barcelonaton FC
As a winger, perhaps. However, if he does come we would probably be playing him in a similar role to how Kone played at the start of last season, where he was a sort of wide forward - which worked (even with him) because it resulted in Lukaku getting more space because the defenders had to give him some of the attention (that was otherwise all on Rom)*.
Bolasie would be a considerable upgrade in that role because he is bigger, faster and more direct than Kone is; him and Lukaku (or him, Lukaku and Deulofeu on the other side) would result in a much quicker, much more direct style than what we had last season (and what we have seen in this pre-season) and we would all see the benefit of it quite soon.
* of course that did require the left back to have a lot of speed to cover most of that flank - which Galloway has, but Baines doesn't.
Kone bagged a hattrick at the start of the season.
Bolasie has scored abar 5 in 3 years.
So no. Not an upgrade
