Brentford goalkeeper David Raya has agreed personal terms with Arsenal.
The Sun says the Spain international has accepted a contract offer from Arsenal and informed both clubs he wishes to make the move.
Arsenal and Brentford are now haggling over a fee, with the Bees demanding 40m to sell Raya.
Arsenal rate the keeper at around half that amount, though there is a confidence a deal will soon be struck.
Should Raya arrive, USA goalkeeper Matt Turner is expected to depart, with Nottingham Forest watching developments.
