The more i look into it the more I think this deal will happen at our terms and our terms only. There are two possible outcomes from here :
1) Napoli go on a rampage and with Koulibaly on the helm go on and reach the UCL final. In that case, ADL will definitely go ahead and ask for some crazy 150 mils for KK and we would say no
2) Napoli very limply go out of UCL in the coming week. In that case, ADL has a depreciating asset in this book with no ticket money and already having spent a lot on transfers. Then he will accept what City has to offer and we get our player
There is also a third case where ADL keeps on haggling for money and the transfer never happens and we go deep into September without a defender. But the noise coming out of City is that they know how ADL is (having gotten their hands burnt quite a few times) and it won't happen again.
The rumours of other defenders are surfacing too. So we may go for Carlos or Ruben or Pau Torres
