Tom Heaton
Heaton has not played a single minute for Aston Villa this season, largely because of the cruciate ligament injury which ruled him out of the majority of 2020.
The 34-year-old has been overtaken by the former Gunners stopper Martinez at Villa Park.
Heaton has a wealth of Premier League experience behind him after making 116 appearances across his time at Burnley and Villa.
He would likely be a short-term option for the Gunners, with his Villa contract running until 2023.
