    The fotball player is creating a negative work (in the system of the other player)

    this means that, if the other player wants to move forward, he first needs to "cancel" the work that is beign done in him (he can do this doing more force on the other player, so the work that he does in the other player is bigger, and now he has positive work, so he is moving).

    negative work is done.

    Explanation:

    Here a football player pushes against another player so the force is applied by the football player so that it will move ahead Now here the force of another player is opposite to his motion so the work done on player by another player is negative.

    So work done is negative because it is done on the system.
