If Pogba is sold for a profit, the money will end up in the club's coffers and eventually end up in the the Glazers' pockets. Remember when Ronaldo was sold for £80M and we spent a small fraction of that money, on players? Gullible fans were convinced that at some stage, that money would be reinvested, but that never happened.
I for one, have observed how things work within our club and can honestly say that while Woodward is our DoF, we won't win the league. If he stays here for the next 10 years, that we won't win for 10 years. His aim is top 4, while spending as little money as possible.
