FC Barcelona manager Xavi Hernandez has warned Cristiano Ronaldo about the quality in the Saudi Pro League.
Ronaldo was unveiled by Al-Nassr last week after joining the club on a free transfer, which reportedly makes him the highest earner in football.
Xavi is no stranger to the middle east, having managed Qatar outfit Al-Sadd for six years before he took charge at the Camp Nou last year.

The former Barcelona star insists that football in the middle east is no walk in the park.
"Ronaldo has signed for one of the best clubs in Saudi Arabia, but it's a challenge," Xavi said, as per the Sun.
"Saudi Arabia has things to improve, but that's the same as in Spain, where we have 200 hundred things to improve.
"Everyone deserves that football should go around the world."
