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
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.
The SPL is indeed a very crazy league, they do not hesitate to make high offers for players who they think are good and worthy of being drawn to play for the club, one of which is Neymar and Benzema, both top players in their time.
It does not rule out the possibility of Messi accepting a contract from Al Ahli, of course Messi will definitely get a big offer, besides all that, currently the Saudi League is consistently building its football, it is likely that more and more top European players will be interested in playing in the Saudi League, very likely.
Earlier, Lionel Messi was offered big money from the Saudi league but he chose to go to America for a better life and he is playing for an American club. Messi is a fairly old player so maybe he will be fully involved in football for another one or two seasons so it remains to be seen whether any club will offer him big money again for this short period of time and whether Lionel Messi will come to the Saudi league even if they do. Ronaldo has extended his contract with Al-Nassr and he will stay at Al-Nassr for two years with a significant salary so if Al-Hilal can bring Messi within these two years then the popularity of the Saudi league will increase a lot and we will see a match between Ronaldo and Messi again.
