We are in a shit position. Our rep has fallen greatly, if this was Poch or Harry Spurs we could be in for elite players at the £70-80m range, right now we are shit so those players have better options. Take Cherki, low release clause but he can pick Pep and massive wages and trophies or us.
Therefore we are put into the wonderkid gamble. We pay more money for less proven players because we have to. Diomande is a Vuskovic type wonderkid, 50% chance he becomes Semenyo or much better and 50% he fails and he will probably cost £70-80m but we are put in a position where we probably have to take the gamble as our only means to start closing the gap back to the top and improving our rep so elite players want to come to us.
This by the way is where the buy cheap buy twice, lowball, low wage ENIC style aspect has hurt us so badly. We have to pay more because the good deals for better players are harder as the players don't want to come to a club that is a mess and they have other options.
