I don’t think Manchester United would make it to top four this season, Because if you look at the team you will understand that Manchester United are going through a phase in the season,
normally Manchester united team didn't start well this season, so there is no doubt that Manchester united team may not make it to top four this season since the team is not yet in good performance, and it is already looking as that this season will be hell for the Manchester united team. And even if Manchester united team will not be able to make it for top 4 this season at least let us see be some improvement from them.
Seems you're just making guesting work here, what shows that manchester united is not in a good form this season? Can you compare thier performance this season and that of last season? Of course there are a lot of changes in the club even if you don't notice that but i can still notice it from here, the only challenge manchester united is having now is goalkeeper and they also need some improvement in thier finishing area because I noticed that they have been having a hard time in scoring in several matches but if it is in terms of performance I don't see anything wrong with thier performance. And yeah, they are expected to do more than this due to thier New signings and is obvious that ever since they bring in those new players Alot of things has changed in the club and I believe with time they would definitely bounce back to a good position.
