Former Arsenal captain William Gallas believes that the arrival of David Raya could unsettle Mikel Arteta’s side.
Aaron Ramsdale had been the first-choice goalkeeper after his arrival from Sheffield United, but that did not stop Arteta brining in Raya from Brentford, on a loan deal that is set to become permanent at the end of the season.
Raya has already made his debut for his new side, and Gallas is unsure if the Spaniard and the England international can share goalkeeping duties over the course of the season.
He told Genting Casino: “The goalkeeper position is one where managers have traditionally not rotated. Sometimes managers play different goalkeepers in different competitions like the Carabao Cup and the FA Cup, but generally, managers always play their best goalkeepers in the biggest games.
“The goalkeeper position is a specialist role. Goalkeepers are crazy! They want to play every single game – they train on their own – they live in their own world. I’m not sure if it is a good idea for managers to rotate their goalkeepers week-to-week, we’ve never seen it before. Time will tell.
“I don’t think it makes a defenders job more difficult when a manager rotates his goalkeepers.
"These players will know each other really well after spending so many hours on the training ground – they will know everything about each other.
“Of course, when you put them together in a match for the first time, that is an environment that you can’t replicate on the training pitch, but there was no problem between Raya and Saliba, Gabriel, and Ben White on Sunday.
"They should all have a telepathic understanding with each other.”
