I think it's much better to say it's difficult to predict the team that will finish in 4th position, cause it's more or less pretty certain that 1st to 3rd is going to be occupied by City, Liverpool and Chelsea, in no particular order yet, cause the season is still quite long, but 4th position is yet to be decided as quite a lot of teams are going to battle themselves for it down to the end which will make things more interesting and intriguing.
The difference point between the four to eight ranks was so narrow. Predicting from now on is very difficult, but I think Man United will fight for this place. The reason is UCL, they would be embarrassed if they couldn't get to UCL next season. Although many other teams are struggling I think Man United are the favourites. Rangnick is starting to change the philosophy of Man United players it seems they are performing better. Although there will still be a lot of games I'm sure they'll be there.
I know how Man United are the favorites for this place but the struggle will still be a fierce rival between Arsenal and Tottenham, Ronaldo's ambition is the UCL next season and there is a threat if he doesn't occupy the 4th EPL standings then Ronaldo will leave I know how he wants the UCL Playing again it's Rangnick who can determine from the philosophy he's changed, and at the moment Man United are still well within reach of his squad.
Sometimes with the season still long they need to be able to do better after spending a lot this season.
