I dont think we will see a repeat of last season because last season's new players ought to have settled so should know what to expect in this league and we have a new ball playing centre half who.should contribute to how quickly we move the ball upfield.
I don't know how Pogba and Bailly will be more settled, they looked pretty settled to me, I kinda expect to see similar from them and I would be content with that, they absolutley weren't the problem last year.
Zlatan is gone and replaced with Lukaku who is a new player that will also need to settle in at United but the upside is he knows the PL and he knows Mourinho so I don't expect much trouble on that front. If he will be alot better than Zlatan, we will have to see especially because Zlatan wasn't really bad, it was mainly our other attackers that need to chip in with more goals.
The point about Mkhitaryan getting more settled is one I indeed also hope for. He should be able to do alot more than he did last season lets hope.
Lindelöf will hopefully also sort out the issue for lack of football ability and build up from the back. I hope for this aswell.
Issue remains that I find us very light in the creative playmaking department. We also still don't have the big star player in attack that can rip open defences and be decisive in big games that I hoped Griezman would be for us.
Fullbacks that offer very little in attack is also still an untackled issue.
A quality DM to balance out our midfield is also still absent. Carrick is a spend force so I'am counting on nothing from that side and unless Jose would find a way to have Axel or Mensah take up the role in a succesive manner it will remain a very big glairing issue for the squad.
All in all would not be a good summer and would not expect that much improvement from last year but at this point I wouldn't be surprised to see it happening.
