Mane deserves to win the award, which he did. Congratulations to the Bayern Munich star, he helped his country Senegal win the nations cup, and to qualify for the world cup, he was also important to his former club Liverpool in all they achieved last season, so he did enough to be the best player in Africa. This is the second time Mane is winning this award, and i do not think this is going to be his last, he is a great player, and he is going to achieve more success in Bayern and Senegal, so i am rooting for him to win the award more than twice, and join legendary players like Yaya Toure and Samuel Eto'o that have won African footballer of the year award more than twice.
He won it before as well, and Bayern basically got the "best African player currently" for 30 million, that's as cheap as it gets, and not like they got him from some second division team, they got him from Liverpool. I guarantee you that Liverpool doesn't need this money, they could literally give him for free, or just donate that 30 million and they would be fine. Sure money is money but they are making so much each year that it wouldn't be a problem for them at all.
This is why Bayern basically got him for free. They lost Lewandowski so it would be something very important to keep Mane of course, but Mane wouldn't be able to score 40 goals a year like Lewa did, this is still great, but not enough.
