I think the main problem is a mixture of over-expectation and poor work by Marotta. We could have bought a title wining set of players with the money we have spent so far, we would however, have gotten no 'WC' players like Kun, we'd have had to rely on sales to cover every other position on the pitch due to the wage pressure, because we'd have had to have matched City's wage offer.
I'll welcome Elia here with open arms because I think he can shine, Nani was and is a pipe-dream. I trust conte's mentality and I also trust that he won't buy players unsuitable for that mentality.
