As with any job, if you do not perform you can be released without pay. However, such a scenario is highly unlikely, especially if you were on an Exposure Tour and the team had the chance to see you play prior to the signing of your contract. Most teams do not release players until the completion of the first half of the season (December), but again it is not likely to happen if you are performing to your capabilities. One piece of advice is to spend time endearing yourself to the team and public. By doing so, even medium level players can be kept on contract—despite deficient play—just because the club and people like you, see that you have assimilated to your environment, and know that you have something to offer the team chemistry.
