I think it's obvious we'll be in the market for a LB, RB and GK. The former two are by Pep's own admission and the latter is painfully obvious to all.
Pep likes midfielders, so I wouldn't put it past him bringing in at least one. Carvalho is a head-scratcher though, linked by the media only because of Pep's brother now being his agent. They've pulled the same trick with just about every good player out there, and it means little. That said, I do think a long term, reliable option will be sought for where Yaya currently holds the fort. Gundogan's injuries and Pep's preference to play him further up the park mean it will have to come from outside, ultimately.
As for strikers, the jury is out. Dybala is such an obvious target it doesn't need to be said. If there's the slightest chance he can be available the club will pounce, make no mistake. Outside that, it all depends on what Sergio will do, if he's gone then you're looking at Aubameyang back in the conversation again, if he stays then you work on making him more in tune with Pep's system and hope that, alongside Jesus and Kelechi, it's enough. My gut feeling is that he could leave and that, either which way, we need something much more to start a serious title push alongside our seriously talented youngsters.
I feel the club will make another run on both Bonucci and/or Laporte, potentially now with offers that the respective clubs may find impossible to refuse. Maybe another attempt for Bellerin, which could well gain traction if Wenger is finally heading out the Arsenal door (which I think he will). Bravo is pretty much gone, too much ill-will there and it's clear he's not settled, I'd expect Moraes or Rulli in as number 1. As for midfielders, Weigl is the obvious target there, Pep is a big fan and he fits right in with our 21-and-under squad refresh. Finally, you're realistically looking at a Grimaldo or Bernat for LB, I think Rose would be low-balling for us and I don't think Pep, or City, will be messing around or gambling with any signings this Summer.
