The transfer market appears blocked at the moment but, should one big move go through, it's expected to trigger a domino effect of other deals throughout Europe.
And the man who could unlock things is Philippe Coutinho. If the Brazilian heads to PSG, as part of the Neymar deal or a separate permanent transfer, it would end Paulo Dybala's hopes of a move to Paris.
Dybala has grown frustrated at moves to Tottenham and Manchester United falling through and would look set to spend another year in Turin. According to 'Sportmediaset', if Juve can't sell the Argentine then they won't be able to fund a move for Mauro Icardi.
If Dybala stays, Icardi's move to Juventus would, in turn, be blocked. This would open the door for another Italian side, namely Roma, to swoop for the unwanted Inter striker. 'Gazzetta dello Sport' claim Roma want to sell Dzeko and replace him with Icardi.
Coutinho is the key to all those deals either going through or being blocked.
