The Magpies shot-stopper has been on the books at Newcastle for six years but has only become a first-team regular in the Premier League this season with Martin Dubravka out injured since the end of the last campaign.
Dubravka is now back fit and available for Steve Bruce, putting Darlow’s place in the starting line-up in jeopardy.
But the 30-year-old has put in some excellent performances this season, including the 0-0 draw against Liverpool last month.
Darlow recently signed a long-term deal with Newcastle, but Arsenal could well tempt him for a move down south with the opportunity to play in Europe.
It would solve an immediate issue for Arteta with the Arsenal boss not able to trust Runarsson. And Darlow has proven more than capable in the Premier League.
