The 22-cap Iran international joined on a loan deal back in September, with the expectation that he was to replace the future outgoing of Said Benrahma, who went on to join West Ham United.
It’s been a struggle for the 27-year-old to establish himself in the Bees’ line-up though, as Thomas Frank has restricted him to just five starts out of his 16 league appearances.
Ghoddos has not yet scored in English Championship, but he played a major part in Brentford’s progression into the fourth round of the FA Cup, scoring and assisting in the team’s 2-1 victory over Middlesbrough.
There was always an option to turn the season-long loan into a permanent deal, and Brentford has acted early to make it official.
