We have wasted A LOT of money on average players over the last few years, that's for sure. Luckily we have also signed few great young players as well and the academy has been producing some excellent talents so we can replace a lot of the deadwood with them. And yes, there's no guarantees that the kids will become top players but at least now they are getting a chance to show what they can do.
If we could somehow manage to sell all the deadwood, pool all that money together and use it to buy Mbappe next summer. How great would that be. Man can dream eh?
