First of all, I am also all for switching to a 4-3-3 as Pogba would reach even higher levels with 2 supporting him in the middle, but I based my proposed team on 4-2-3-1 being our most used formation up to this point.
I know everyone is reluctant because he has been spending most of the seasons on the sidelines for the last couple years but like I mentioned, I don’t think United are too concerned about that & it’s based on nothing, but I feel Bale could overcome his injuries.
But other than that, why is that a weak team? Our defensive record has been pretty good since the 2015/16 season. Vale has transformed into one of the best right backs in the league. Jones & Bailly formed a pretty reliable CB partnership earlier in the season and we’d also have Lindelöf, Smalling & Rojo in the squad. As for the left back area, I’ve always been supportive of Shaw and it’s great to see him getting opportunities and taking them recently. He needs to keep up what he’s been doing for the remainder of the season and we won’t have any issues in his position at all (although I’d still like to see us sign Sessegnon and loan him back to Fulham for a season). Then, onto the midfield: Pogba & Matic have also formed a very good duo, but like you all claimed, a midfield of 3 would be even better. We should probably buy someone here since Herrera hasn’t been the same this season (although I think he’s the type of player that needs a run of games to pick up form). As for the front three, Martial is still only 22 but already quality and for me he’s a proper left winger, unlike Rashford so I’d rather start the Frenchman there (I’m also a big admirer of Marcus but I feel Anthony edges him at the moment, especially on the left). He also looks to have a good understanding with Lukaku. And then we’d have Bale starting on the right.
Getting Bale, Ricardo Pereira (someone mentioned him and I also think he’d be perfect), Sessegnon & a new CM would be considered a great window for me and we’d be good to go.
