Brentford boss Thomas Frank admits David Raya has rejected a new contract offer.
Spain international David Raya, 27, arrived at Brentford in the summer of 2019.
Since then, the goalkeeper has developed into a key player. Recently, he has been linked with Tottenham, Chelsea and Manchester United .
Raya's contract expires in the summer of 2024 and it has previously been reported that he snubbed an extension.
Bees manager Frank confirmed: "I think that if he declines twice, it is unfortunately a signal. We presented two really good offers but that's okay, it's a free world. We cannot force anyone.
"David has been fantastic for us. I think he is one of the best goalkeepers in this league right now. He is very focused and I am happy for every day he is here.
"I hope he will stay forever but it looks like it could be difficult given the contract situation. He must cost at least 40m.
"If he had three years left (on his contract) it would have been 70m. How much did Kepa cost ? He's at least as good as him."
