He's allready earning quite alot. Most of those "big teams" are inferior to us. Barcelona cannot afford him because they make losses with their current wages. And Pogba isnt going to take a step down and go to the EPL.

And we have Vidal who serves as a nice example on why you get fucking rekt if you leave us.
