nah mate,its a little more complex. First of all Akanji has every right to give his opinion. Another thing is to put out the effort during tournament and nothing i seen from Akanji so far tells me he would not.
Its not comparable what You are doing sir and how much earns to the issue. Earnings of top footballers are high because of many factors. The competition is crazy for young people. They need to mature and put the hard work at training for years. They need to choose work and training over pleasures, friends, etc. The regime becomes increasingly strict from a younger and younger age. On top of that, around the age of 12–15, you have to significantly limit other activities, including education. At that point, it becomes a black-and-white choice — either I pursue the path of becoming a high-earning footballer, or I continue my education at a serious level. And what if, 3 to 6 years later, the footballer gets injured and can’t return to the sport? It’s not anyone’s fault, but the person ends up unable to be a footballer and also not particularly well-educated. It’s a difficult situation.
In short - maybe you working hard now because you were rather easy going when young and Manuel do not? Etc. There are many possibilities, but the point is the football players are right to earn their money and it’s not an argument to limit their freedom of speech in any way.
