Brentford coach Thomas Frank has admitted that his goalkeeper David Raya could be sold by this summer after both parties failed to agree on terms of a new contract. The Spain goalkeeper’s contract expires in 2024, but he has failed to commit to a new deal. Earlier this week, he revealed that he had turned down two new offers from the Bees, leading to speculations that he could be sold this summer. The 27-year-old has proven to be one of the Premier League’s finest stoppers since Brentford were promoted to the Premier League in 2021, and his performance has attracted the interest of Manchester United and Tottenham.

We can’t force anyone. “That said, David has been amazing for us, coming from Blackburn three-and-a-half years ago. “In the first season, for me, he was the best ‘keeper in the Championship and then was involved in the play-off final. He made a mistake there, but we told him, ‘you will come back stronger’, and the year after, we did it. “He has taken that form into the Premier League, and I think he’s one of the best ‘keepers in this league right now. He’s very focused, and every day he’s here, I’m happy. “He’s one of the captains, and he is leading with his performances and his behaviour. He’s a top character. “I hope he will stay forever, but it looks like it could be difficult with the contract situation. “He must be [worth] at least £40m plus. If he had three years [left on his contract], it would be £70m. How much was Kepa? He is at least as good as him.”
