Arsenal legend David Seaman can't see Aaron Ramsdale wanting to play second fiddle to David Raya long-term/
But he believes a January departure is unlikely for the England goalkeeper.
"If he's not playing [for Arsenal], it's going to affect his [England] chances," Seaman, who is coaching at Arsenal, told BBC Radio 5 Live.
"Going into next summer, where Aaron is really pushing to become England goalkeeper - he needs to be playing.
"If Aaron goes in at the weekend, then he's left out for the next game, then we know who Mikel's number one is," added Seaman, who won three league titles in 13 years at the Gunners.
"It's not good for Aaron. He's a top-class goalkeeper, there's no doubt about that.
"I think January will be a bit too soon [for a move away].
"It's the game after this weekend, that's where we will find a lot of answers. From what Mikel was saying when he brought Raya in, when he talked about rotating goalkeepers in games, which I still found a bit bizarre, we'll have to wait and see after this game.
"Aaron's too good to be a number two, that is for sure."
