Every player's contract generally has additional terms, such as goal bonus, which are commonly found in the contracts of strikers and midfielders. Other players will have an assist bonus in their contracts. The goalkeeper has a clean sheet bonus in the contract. The contract of substitute players usually stipulates the appearance fee, and the contract of young players has a percentage increase in annual salary.
Sometimes the club will give extra rewards, such as winning bonuses, winning league prizes, winning champions league prizes and so on.
Of course, besides money, the player who scored the goal will be praised in the dressing room and even at the post-match press conference, which can also improve his position in the club.
