Seriously I think in different scenario we shouldn't sell, but in our current situation, if someone pays close to 100 m it's no brainer. With him gone we could contract two top players or even 3 if we do it wisely. It's like 60m plus Valente plus the amortization saved and big contract.
The problem is of course the same, do we really trust the current management to choose the right options? Probably not, but if that's the case then we already are a lost case. This team needs striker, midfielder, LW and LB plus De Ligt replacement if he leaves. This is just too much.
