For starters, this would be my dream manchester united after Griezmann deal didn't go though. Pogba and Dybala have a really great relationship and I feel Dybala would thrive with the players around him creating a lot of space for other players to score or assist another player. 
Secondly, I feel we won't sign Danny Rose but I think he will do really well for United and him and Luke Shaw are interchangeable for whatever team we are playing against and the both are English. 
Next, I will talk about Anthony Martial I feel he will thrive with the players around him like I said earlier he will have a lot of space because of the players around him which is why I think he hasn't been doing the job for United; Ivan Perisic Will bring a lot of experience and he is really good at crossing I feel Morata will score a lot of goals with him and Mkhitaryan crossing and creating chances.
I know some people will be a little upset with Ross Barkley he is very unpopular upon United fan but if you think about it, he is probably one of the better English squad players that can play the off game for United and or sub. he ended the season with 5 goals and 8 assist another thing is he can fill the homegrown quota. 
lastly, James Ward-Prowse would be another great squad player for United and I think he could really change the game off the bench with his crossing, set pieces, and his high passing accuracy. I think he could learn a lot from Herrera and also is English.
