I think not have chance for Dybala will join Inter Milan next season after success transfer and get back Romelu Lukaku from Chelsea with loan option. Maybe long negotiation between Dybala and Inter Milan management and not get agreement with Dybala, not any other issues except moving to Inter Milan for Dybala because he not on the list window transfer player from other team on Serie A. Will he plays on Primer League and La Liga for next season? Dybala is good option because he has free transfer player and team not needed to spent much money for getting Dybala sign's.
Dybala is now in a difficult position.
It's quite difficult to force Inter now that they have Lukaku in the squad. He had also offered himself to Barcelona but was flatly rejected by Xavi which made things more complicated for Dybala.
I think now he has to look for other alternatives or indeed take back his words and hope Juventus give him another contract after being rejected some time ago.
Dybala's future is still a big question after the rumored Dybala joining Inter finally failed. Since Inter have managed to get Lukaku from Chelsea,
now there are still some big clubs waiting for an answer from Dybala. Like Real Madrid, AC Milan and AS Roma reportedly want Dybala. When in fact
Dybala wanted to move to Barcelona, but it looks like Xavi prefers Lewandowski over Dybala. So Dybala has to consider other teams that still want him.
But to rejoin Juventus seems impossible, because Dybala would be very embarrassed if he had to retract his words to part with Juventus.
