Signed on a three-year deal from Dijon in France for an undosclosed fee during the 2017 summer transfer window, Mamadou is a strong and pacey forward who can use both feet; able to play centrally or out wide.
He arrived at Oakwell with a growing reputation on the continent, after scoring 10 goals on loan at Clermont.
The 22-year-old has also represented Senegal at U20 level.
'Mama' notched his first Reds goal against Millwall in a 3-1 win and after slowly getting to grips with his new surroundings, found himself a key figure in Heckingbottom's plans.
