Only SPL offer mega contracts like Al Nassr's given to Cristiano. Barcelona president said he's trying to sign Messi again but Al Ahli's in talks with Messi because his Inter Miami contract's ending in Dec 25. If Messi wants new experience & mega money he'll go to SPL
I won't advise Messi to go back to Barcelona if he doesn't want to experience same thing Ronaldo experienced at Manchester United when he went back there out of love. Money aside but I think Messi and Ronaldo are no more fit to in Europe again, they will only struggle to play well, I know they will contribute to the team but they can't give 100% anymore and these European teams demands a lot.
Al Nassr did give an extraordinary contract to Cristiano Ronaldo, in this case no one can imagine that at his age which is no longer prime, Ronaldo can get such a big offer, it is truly extraordinary.
After all the goals Ronaldo managed to score for them I don't think they did the wrong thing by giving him that offer. He deserves it despite being 40, who can imagine a guy as old as that can score as many goals and even win the highest goal scorer award for two consecutive seasons. Ronaldo might be old but the goal scoring instinct are still very much intact and soon he will reach 100 goals for Al Nassr in just how many seasons.
I believe if Al Nassr team should be balanced they will definitely dominate the league with all Ronaldo's goals but they have a very poor in their defense which is the cause of their inconsistent performance. If they can improve their defense I don't see a reason why they can't win a trophy.
