Hakon Valdimarsson says he has been able to "improve in all areas" at Brentford after signing a new long-term contract extension until June 2030, with a club option for a further two years.
The 24-year-old goalkeeper joined the Bees in January 2024 from Allsvenskan side Elfsborg, penning an initial deal which was due to run until June 2028.
Since then, the Iceland international has made 12 appearances in all competitions. He also played a key role in the club's Carabao Cup quarter-final run this season, having featured in every tie and saved two penalties in a third-round shootout victory over Aston Villa.
"I'm very happy to stay here for two more years," he said after signing his new contract. "The last two-and-a-half years here have been very good for me.
"Since Keith Andrews has taken over, I've enjoyed my time and felt very happy here. Our relationship is good, we speak a lot. He is a very good manager, a good guy and always nice to speak to.
"I feel a completely different player to when I arrived here, I've improved in all areas as a goalkeeper. Now I just want to keep getting better and try to play as many games as I can."
Brentford boss Andrews added: "I'm delighted Hakon is signing a new deal. People maybe don't recognise what goes on behind the scenes and the importance of certain players on this journey.
"Hakon is a big part of the fabric of this football club, he understands it. He is a very liked individual, he has some very close connections in the club, he is an outstanding goalkeeper.
"We are really happy that he has signed a new deal here."
