The Eredivisie giants are looking for a long-term replacement for 39-year-old Remko Pasveer, whose current deal expires next summer.
Raya has been a regular for Brentford since moving to the club in 2019, making 138 appearances in all competitions.
The Spaniard was instrumental in Brentford’s historic promotion to the Premier League. He also impressed during the 2021/22 season, keeping eight clean sheets in 24 games.
Raya made his senior team debut with the Spanish national team earlier this year, and he was also part of the 2022 World Cup squad, where he served as an understudy to Unai Simon.
The 27-year-old’s contract expires in 2024, and the Bees have yet to discuss his renewal.
Ajax have already contacted Raya’s entourage to let them know of their interest, with the Dutch champions keen on signing a new shot-stopper in January.
