New England Revolution coach Bruce Arena has confirmed Matt Turner is on his way to Arsenal.
The Gunners agreed a deal with the MLS side worth around £5million up front for the 27-year-old, which could rise with add-ons and also includes a 10 per cent sell-on fee.
Arena confirmed: "If it hasn't been fully executed, it will be."
Turner is expected to join up with the first-team squad in the summer, allowing current No2 goalkeeper Bernd Leno to leave the club.
The German lost his place in Mikel Arteta's side following the arrival of Aaron Ramsdale during last summer's transfer window.
