Brentford boss Thomas Frank says he expects goalkeeper David Raya to complete a move to Arsenal.
The 27-year-old Spaniard is reportedly set to join the Gunners on loan where he will provide competition for England keeper Aaron Ramsdale.
Raya, who has one year left on his contract, joined Brentford when they were in the Championship in 2019 for a fee in the region of £3m.
He kept 11 Premier League clean sheets last season as the Bees finished ninth.
In July, Brentford boss Frank said it was an "open secret" the club would be willing to sell Raya and that they would want £40m for the Spaniard.
