Few players I have seen people talking about that I do not want to join Manchester United this summer.
Lukaku - Everton will want a lot of money for him, around £50-60million I'm guessing, which I think is way too much for a player that doesn't turn up to big games, don't get me wrong he is a good striker, but not the complete striker United need. We need a player that can score against the top 6 and Lukaku has not shown that.
Matic / Dier - I believe there are other central midfielders we can buy that can hold the ball up, to me if we buy Matic / Dier then may as well just get rid of Carrick, because they are pretty much alike. Would prefer United to buy Fabinho from Monaco.
Mbappe - Monaco would want a huge asking price for this guy, and we already have Rashford, what's the point out-casting the lad for someone that has developed a bit faster. Waste of money and would prefer Griezmann, who is still young and will help Rashford develop a lot more, to become the complete striker.
James - He has potential but a risk player in my opinion, he'll either be class or terrible. Not worth the money Real Madrid will ask for to be honest, as he cannot fit into their starting XI. Also, Mata will never be played if he comes, and the difference between these two players is that Mata has proved himself in the premier league and is consistent.
Kroos - Don't get me wrong, he is a class midfielder, but quite slow, and I believe there are better options. Herrera and Pogba should stay as the central two just ahead of a more defensive midfielder (Fabinho). No need for Kroos. But heck, I'd swap him for Fellaini if that is possible?
Hart - Never. Makes too many mistakes, and because we'd be buying from Manchester City, they'd want a higher buying price. There are many other options for United. Romero as proved himself and in my opinion he's better than Hart. We also have Pereira, who has potential and a good game against Crystal Palace last Sunday. Never rated Hart, and never will.
Those are my thoughts anyway.
