but in my opinion Ronaldo will certainly have the potential to extend his contract because if read the news of course there is a lot of news that directs that Ronaldo has great potential to extend his contract of course currently it is still in the negotiation stage so we'll just have to see later.
Cristiano Ronaldo is still better than many young players but the fact is effects of ageing on his body physic strength surely rests in worse performances over years. Soon his body will say no with playing as a player and his performances will become worse enough, his appearances will decline considerably so that he will make his retirement decision. That will be surely an extremely tough decision for an ambitious player like him.
Whether Ronaldo signs a new contract with Al Nassr is very unknown but this summer is not good time for him to leave Saudi Professional League and return to any league in Europe. Main reason is Ronaldo needs to play as most regularly as possible in order to prepare for World Cup 2026 tournament next summer.
If he won't sign a new contract with Al Nassr, he will sign one with another club in Saudi Arabia, at least in this summer and play for at least one more season there.
