It was Mane's decision to go, he's 30 and this could be his final World Cup with Senegal, I'm not sure the injury is as serious as we thought given that there is still a week until the World Cup for him to at least recover since he was flown to Africa for herbal treatments, we know how far Senegal is willing to go to ensure the country captain goes to the World Cup. Because of the timing of the World Cup, he may miss the first game. I recall a similar scenario with Drogba, who was sidelined for four weeks due to a hamstring injury. He went to Africa for herbal treatment and recovered just in time for our Champions League game. No players were sacrificed, his slot was untouchable.

Well your points of view are very good, I also see the point of view of the coach from Senegal and I see the point of view of Mane, I also understand why he went to Africa to receive his herbs to heal quickly, and I hope that can recover and be ready for the first game, however we see many points of view and above all the most important is health, which, it is not very clear how serious his injury is, what I do understand is that it is or could be his last World Cup and he doesn't want to go wrong with his people, I think that's what moves him the most, that's why I think he's doing all this, I really admire soccer players like him.
Unfortunately, he did not make it to the world cup; the injury was not as minor as we first thought; I believe he was blinded by the fact that this was likely to be his last world cup because he is already 30+ and not sure if he would be around or age wise to make it to the next one. To demonstrate how bad his condition is, he is currently on clutches. It's heartbreaking to see Senegal in this state, as he was their only hope of a positive outcome from the World Cup.
Portugal vrs Ghana ? This is a joke, There's no bloody way on earth Portugal will loss to Ghana.
really? Who would have thought that the Saudis would come back from a goal down to beat Argentina in a world cup tournament? The Ghana team is more experienced; it will be a difficult game for Portugal as well, and I will not be surprised if Ghana wins; sometimes you only need 2-3 goal chances to win a game, as Saudis did.
