Have Arsenal signed their way into a problem?
The Gunners have brought in Brentford keeper David Raya on a season-long loan with the option to make the move permanent.
Raya excelled for the Bees last term, helping his side to their highest league finish since 1938.
But Aaron Ramsdale also had an excellent campaign, keeping 14 clean sheets across 38 matches as Arsenal finished runners-up in the Premier League.
There can only be one true number one - and former Manchester United keeper Peter Schmeichel believes Raya's signing "could be a problem" for Mikel Arteta's side.
