Honestly, I think De Jong to Manchester United is a good deal and despite the huge price tag placed on him it is still worth the money and stress so far in getting the deal. He is a good midfielder, he controls the ball fine and has good passing accuracy but I think they also need to work hard on recruiting defenders cause their defending was very poor last season and need to replace some dead woods with young and fast defenders.
Still a bit overpriced but Barcelona is in deep financial situation recently, kinda understand that they are trying to squeeze as much as possible from Manchester United. Well considering that currently the team is in deep shit of needs for a great midfielder, its kinda worth the price provided if he could play atleast that good as when he played in Barcelona
