I'm a big fan of what I've seen of Bellingham for Dortmund and England, although I'm still not sure how he fits in to the way we play. The concern is he'd become another Haaland - excellent player we somehow decide to bypass until you wonder why he bothers.
Although with a year of coaching, I'm sure we could stop him making the driving runs and just pass it back to the centre halves instead...
I just don't see Pep changing his style enough to allow someone like Bellingham driving forward, with Haaland running ahead of him, as that doesn't suggest control.
