What might happen if a player violates a performance clause?

If a player violates a performance clause, they could face a reduction in salary or bonuses because performance clauses are typically put in place to set specific targets, such as scoring a certain number of goals, playing a specified number of matches, or achieving certain performance metrics. When a player fails to meet these criteria, the financial penalties serve as a deterrent to ensure that players remain focused and committed to their performance. Such consequences can significantly impact a player's earnings and can be enforced through the contractual obligations that both the player and the club have agreed upon.

The other options do not align with the typical ramifications for violating performance clauses. Receiving a bonus would contradict the purpose of such clauses. Automatic team switches are generally unrelated to performance issues unless combined with broader contract terms. Additional training might be a response to performance issues but does not fit the consequences outlined by performance clauses. Therefore, the correct response captures the financial repercussions that are most likely to follow a violation of a performance clause.
