Arsenal want to sign £40million-rated Brentford goalkeeper David Raya as back-up for Aaron Ramsdale.
The Gunners are frontrunners after Brentford rejected Bayern Munich’s offer of a loan deal with the option to sign Raya permanently.
It is understood the Spaniard would not replace Ramsdale as No 1, but would be used in cup competitions and provide greater competition for the England international.
Mikel Arteta is believed to have doubts over his No 2 goalkeeper Matt Turner, who has been linked with a move to Nottingham Forest. However, Brentford value Raya - who turns 28 next month - at £40m, whereas Arsenal want a fee closer to the £30m mark.
