At least in the United States, money paid to anyone indicates the value society places on that person or their work. Sad to say, football is valued much higher than teaching, or almost any other kind of work. But, a footballer has a short work life so he may receive the money based on the amount of time he plays, and the amount of money his team receives because of his efforts.

I see that he don't deserve all of it even there are too much people who really suffering ..also who really deserve a little from this money

No , it's far too much money.
