There seems to be a standoff now.
Juventus have bought Higuain (by all accounts) for a hefty €96m. No way they'd do that without the intention of selling Pogba. It's too much for him and for them. It will also allow them to save face when he goes.
You also have to consider Napoli won't want it confirming they have the best part of €100m to spend, or they'll be faced with an Andy Carroll to Liverpool situation.
Juventus will obviously try and get as much money as they can for Pogba. Raiola's fee seems to be the problem, we have to pay that as well. The fee has always been set at roughly £105m, I think, and they aren't budging on that.
The reality is, long term, whether he costs £90m or £100m - it makes no difference.
