Arsenal have confirmed the season-long loan signing of the goalkeeper David Raya from Brentford. The 27-year-old joins after two successful seasons in the Premier League with Brentford and will compete with the England international Aaron Ramsdale for the No 1 spot.

An announcement on Arsenal’s website said “there is an option to make the move permanent”, and Brentford expect this to be exercised. The deal has been structured this way for financial fair play reasons.

Brentford’s director of football, Phil Giles, said: “I’m not expecting to see David back at Brentford, although if ever that happened then of course the opportunity to work with such a high-class goalkeeper for up to two more years would in many ways be an unexpected bonus for us. All parties [want] to make this a permanent transfer as soon as practically possible.”

Raya has also signed a new two-year deal with Brentford with an option for a third, which the club described as a “fall-back option” should his Arsenal move not be made permanent.

Leicester have signed Cesare Casedei on a season’s loan from Chelsea. The 20-year-old spent the second half of last season on loan at Reading. The Italy midfielder won the Golden Ball, the most valuable player award and Golden Boot at the Under-20 World Cup in Argentina that finished in June.
