During his 10-year stint at West Ham, Antonio made 323 appearances and scored 83 goals, making him the club's leading Premier League goalscorer. However, the club chose to release him at the end of his contract.
Antonio is now seeking a new club and has started training with Brentford's first team, led by coach Keith Andrews. This will allow him to stay fit and potentially attract a new team to sign him.
Antonio made a slow comeback to the pitch, returning to action for Jamaica in June. His vast top-flight experience could be beneficial for a team like Brentford, and a short-term, low-wage deal may be possible.
