Former Tottenham man Georges-Kevin Nkoudou is also proving his worth and is close behind two of the Saudi Pro League's biggest stars.
The Cameroon international spent three years in north London but featured just 27 times for the club in all competitions.
Nkoudou enjoyed a lot more success with his move to Besiktas as he amassed 30 goal contributions in 108 appearances.
And he has gone one step further at Saudi side Damac, with the winger already scoring 14 goals in his first 16 league matches.
This tally puts him third in the Saudi Pro League's top scorer charts, leaving him just one behind Al Hilal's Mitrovic.

Nkoudou scored a hat-trick in Damac's 4-2 win against Abha, making him the tenth player to do so in the league this term.
Ronaldo and Mitrovic are also part of that list, with all three set to compete for the Golden Boot.
