What we need is a calm defender, a defensively solid midfielder and two attacking players to bring us some goals. Can't see us making more than four signings, except from a couple of youngsters (for instance Ryan Sessegnon). In defense, Michael Keane would be a brilliant addition to our squad. A lot of people seem to doubt whether he is good enough to be a starter for Manchester United from day one, but I think he has abilities that would make him a perfect partner to Bailly. Looking back to the duo of Vidic and Ferdinand, Bailly is obviously our new Vidic in terms of playing style. In a central defense duo you need complementary abilities, and looking at our squad I would say that Blind is the only centre back that suit as a partner to Bailly. Keane has a much calmer style of defending than the likes of Smalling, Jones and Rojo, and he rarely puts himself in situations where he has to make a last second tackle. He can fall back when Bailly breaks out of the defensive line, and sweep up in the space that he leaves behind him.
In midfield, we need a no-bullshit player that can play in a 433 system in the biggest away games. However, in 9 out of 10 games I would like us to play a more offensive 4231, where Pogba-Herrera should be our preferred duo. This means that the new midfielder will have to be put on the bench in most games, our play in other positions. In short, we need a player for the John Obi Mikel role. I can see us bring in Fabinho to fill this role, since he can be backup for Valencia, Herrera and Pogba when we play 4231.
Our main problem this season has been the lack of goals, and I would like us to bring in James Rodriguez and Alexis Sanchez to add some goals to our attack. Two world class players that are available for reasonable prices (50 and 60 million pounds?) when you see Everton wanting 100 million for Lukaku. This would mean that Rashford is our first choice striker, with Martial as a backup and also the possibility of putting Sanchez up top. Both of them will suit Mourinho as they put in a shift defensively, much more than they have been given credit for lately. Give them a role as star players on a team that wins matches, and they have the warrior mentality that Mourinho likes. This would leave us with this title winning starting 11 in most games:
De Gea
Valencia - Bailly - Keane - Shaw/Darmian
Herrera - Pogba
Mkhitaryan - James - Sanchez
Rashford
