Reus is as unrealistic for us as it gets. Dortmund has already said they won't even consider selling him and Reus has absolutley no reason to join us either especially because he knows he can make a better move next year when his clause kicks in. On top of that he has said that he is happy at Dortmund and for the moment he doesn't want to play anywhere else. Good luck getting that guy in the summer, I think you'll have as much chance of getting Ronaldo or Messi in the summer.
On top of that we are currently playing in a formation that suits 2 midfielders and not 3, what will you do with Mata, Kagawa, Rooney etc that could play as a number 10 ? Even if you wanted to convert to a 3 man midfield, if you sign Kroos and Carvalho you already have all the midfielders you need to play like that with Fellaini. The squad depth will come from Carrick, Cleverley and Fletcher (the club is not going to sell them and it be a complete wast to have them on the wagelist if you are never going to play them). In short there is no need for us to sign 3 midfielders, you can sign Kroos+Carvalho, you can sign Carvalho+Gundogan and you can sign Kroos+Gundogan but there is absolutley no reason to sign all 3 of them, its pure overkill !
Carrick is 32, Fletcher is 30 (both will need to be moved on eventually as age is catching up with them) do you suggest Manchester United keep this caliber of players given their age and also injury history (Fletcher?) do you see them winning games, against midfields like Man City, Chelsea, Arsenal?.
Kroos 24, Gundogan 23, Carvalho 22.
You have to refresh the squad, move on aging players who can't really contribute much to the team, we haven't bought the right midfielders in a long time bar Fellaini, I class Mata as a forward.
Mata and Rooney are "Forwards", Mata especially he does little defensively, look anywhere in Europe right now, the game is won in the midfield, then you have one quality forward, that's why RVP and Rooney doesn't work, the balance is completely wrong with the team.
Yet David Moyes has to compensate for the lack of the midfield this year, there is a lot to fix with an aging team, we need a midfielder that drives at players, one that can pass, and a defensive minded one, it's as simple as that, you can't prepare for a game against Stoke the same as Chelsea, you need different kinds of players in your squad.
Kagawa I very much doubt will be a Manchester United player next season, the same with Giggs, I can see Fletcher being moved on, Carrick I feel has a part to play.
A midfield 3 isn't exactly going to be a solution for each game, but what you do need is players who are flexible, can rotate, and be played in various systems.
The team used to mix age and experience, but now it's Carrick being paired with Cleverley, or Fletcher and Fellaini, it doesn't work the players do not work in tandem, there it's round pegs in square holes, how can you play players who don't compliment a play-style or don't help with the balance of the team? if the team doesn't strengthen defensively and in the midfield by the end of the year next year it won't be a title challenge, it'll be top four at best.
There's no dynamism to our play, Mata is not a midfielder anyway, he'll be adapted into a #10 with either RVP or Rooney up-top (can't have both) or Mata will be made into an inverted winger as a RW, as that would help his chances playing in the Spain national team too.
The only reason we are keeping Cleverley is to meet the quota of home-grown players, plus Gundogan, Kroos and Carvalho are all different types of players, just as Fellaini is, they all can play in the same systems as can any player, but it's finding the harmony between what the opponent brings to the table too, you need a squad of 4-6 players in midfield, and midfield is where you win games.
