Both players had a great year in 2019, no doubt but i'll disagree with you on who deserves it more. Mahrez might have performed well in the African Nation Cup but i wouldnt say he performed better because his country won the tournament.

In regards to the trophies won, Mahrez quite alright won four but do you think the UEFa Super Cup and Club World Cup Mane won counts for nothing?

In the aspects of individual performance for club and country Mane edges Mahrez hands down, the stats tells that. Remove Mahrez goals for City, i dont think there'll be much of a difference. But removing Mane's goal, Liverpool may not accomplished what they did as Mane scored the more crucial goals.

The awards also says best African player. On an individual level Mane had a better year, even FIFA recognized that as he made top in the Balon d'Or.
