Brentford winger Josh Clarke has signed a new one-year contract.
The 19-year-old made his league debut for the Bees against Colchester in the penultimate game of last season.
Griffin Park boss Mark Warburton told the club website: "Josh has made significant progress in a short period of time.
"The fact that Josh has now fully joined our first-team squad is testament indeed to his work ethic, desire and determination to make a career in the game.
"I would like to congratulate Josh on his achievements to date and look forward to him continuing his progress in the months ahead."
