The Liverpool forward picked up the man-of-the-match award as they beat Chelsea on penalties on Wednesday night.
The Senegal international scored twice as the match ended 2-2 after extra-time.
The 27-year-old did not get to take a spot kick, though, as he was substituted before the penalty shoot-out took place.
But it was his heartwarming gesture that had everyone talking following the game.
While sitting on the bench, he called over one of the ballboys and gave him his shirt before giving him a hug.
The ballboy looked delighted as he walked off with Mane’s Liverpool kit.
It is not the first time that the forward has proved he is an all-round good guy.
Mane spent time during his break before the new season visiting the construction site of a school he is building in Senegal.
He was late joining up with the rest of the Liverpool squad due to his involvement in the Africa Cup of Nations.
