Keita, who came through the ranks at hometown club Horoya AC, has been on an upward trajectory since joining French club FC Istres in 2013, going on to play for Red Bull Salzburg and then RB Leipzig.
Now awaiting a transfer to Liverpool, the 22-year-old has made the bold claim and insists that he wants to be even better than his idol, Manchester City midfielder Yaya Toure.
"I want to become the best African player in the world," Keita is quoted by The Mirror as saying. "My idol from Africa is Toure. He is strong, works hard and has made it to the very top.
"When I am on the field, I want to think that I am the best. It's not for myself, it's for the team. Once I do that, I can feel good."
