Here Neymar's entrance is just for the media coverage and having good impact in South American market as well because if they have Messi then surely it's going to be better for them but after his rejection they bring another big name no doubt he will give time to league and also try his best for good performance which is main target but still not many expectations because of his history.
The Saudi League has spent a lot of money to bring star players like Ronaldo, Neymar and Benzema to Saudi, not just for good performances. If they want good performance and only want to improve their league, they could spend less money and bring talented players to Saudi. They brought in star players like Neymar, Benzema and Ronaldo because they wanted to tell the world about the Saudi League. Neymar and Ronaldo have huge fan bases. And this is why the Saudi League is expanding rapidly. We knew very little about the Saudi League even last year. We didn't talk much about this league. But this year we all know more or less about the Saudi League. Also keep track of the matches. Saudi Arabia is planning long-term. Gradually they will popularize the Saudi League.
