Nobody is saying that we shouldn't sell Mata, but why did we need to sell him to United? Yes we got more money than most would be willing to pay him but we don't need it. It would have been much better for us to sell him for less in the summer and take a small loss to screw United over. The only reason it would be sensible to sell him to those ******* if we reinvest that money now into a big player.
Not really, if we kept hold of him for another 6 months he doesn't play a lot, doesn't go to the world cup his value halves. We don't have to play Utd again this season and by selling him for so much we can build our squad to make it better. Even with Mata at Utd we are in a much better position this season, next season and for the foreseable future i am not worried.
