Basically all the money from sales was promised to Poch (itk)...and considering who was going (ie some high value players + squad fillers/failures) was a pretty sum of money (circa £170m). As I have said before on paper it all looks good, to execute is a miriad of conversations, negotiation s and transactions. No buttons saying sell and buy.
Levy did nothing to block any of this and if he was blocking by overvaluing one of our players or thinking an incoming target was to expensive it was with the full agreement and understanding of Poch. If there was any falling out over any of it we'd certainly know about it.
Naturally as a professional coach with the urge to press on it is not surprising that you show some signs of frustration as your basically left with the same old same old from last season.
Let's not forget though that Levy (itk) gave Poch carte blanche to do as he wanted with the squad (he c.ould of sold Kane if he wanted), that's a massively high level of trust from the chairman, and why wouldn't you trust Poch, he as earned it. Poch is also in full realisation that that level of control is a rarity as a coach/manger, which hopefully filters into his grass is greener thoughts.
