It was really surprising even though previously Sadio Mane was rumored to Al-Ahli and it seems he refused to play with his former Liverpool team-mate, Roberto Firmino. But I think it's quite the right decision so as to make the squad depth for each team in the Saudi league competitive. On the other hand, at this time it can be said that Al-Nassr has not found the right left wing and Sadio Mane can provide his services through that position. With that age, it can be said that as a footballer, Sadio Mane has won everything and he doesn't need to chase further ambitions too much. Apart from that, now the decision rests with Sadio Mane, whether he wants to join other European players in the Saudi league or not.
