I can assume that Roma reasonably assumed that Dybala could get an offer from Saudi Arabia, in which case they would receive a ridiculous compensation of 12 million. I wonder how much they increased Dybal's salary to motivate him to extend the contract. With such a shortage of strikers in many clubs, the demand for even the "non-star" Dybala must have increased.
Dybala is very happy in roma. Chelsea has been trying to get him from as roma but dybala has rejected it. My guess if arabian club has zero chance to get him. Even chelsea was not able to signing him as a new player and i think that dybala will reject an offer from saudi without even try to consider it. Im feeling no doubt if dybala will not leave from the club. He will stay in as roma for another season under jose mourinho. As roma has a plan to increase his release clause in the new contract.
From my personal view that indeed, basically Dybala is not suitable to play in the Premier League with pressure and difficult gameplay. Because after all, Dybala also has a bad injury history so, playing in Serie A is indeed the right place. But, if there is a Saudi Professional League club that makes an offer to Dybala, then I personally believe Dybala could have accepted the offer. But indeed, if it doesn't happen at this moment, then of course there is still a chance in the upcoming transfer market. In essence, I believe that one day Dybala will leave Serie A, and play in another league and it is very possible to play in the Saudi Professional League.
I think you are bringing up some important points here that a player like Dybala should consider. The Premier League is way more intense physically and he has never been a player who was very good at taking hard tackles against him without pain and sometimes even injury. But it is easier said than done when it comes to those decisions. When players are close to their 30s and they get a chance to play in the Premier League, which player would really decide against it? The money is probably also better for him than at Roma, but I believe Mourinho would be quite disappointed about it.
