Hatters tipped to be interested in signing former keeper from Hibernian
He went on loan to Accrington, before moving to Luton in January 2017, aged 22, as Town brought in Stuart Moore too, once Christian Walton was recalled by parent club Brighton & Hove Albion.
Macey played 11 times for the Hatters, keeping four clean sheets, but he too had to head back, to sit on the bench for the Gunners after they had injuries of their own.
He went on to make two appearances for the senior side in the 2017-18 campaign, starting the Carabao Cup against Norwich and the Europa League goalless draw with Red Star.
Macey then spent the 2018-19 season on loan at Plymouth Argyle, featuring 38 times, snapped up by Hibs in January 2021.
The keeper made 44 appearances for the Easter Road club last term, but with Scottish international David Marshall joining this summer, and expected to take the number one jersey, the Scottish Courier has reported he might look to move for first team football, with Luton tipped to be interested, plus fellow SPL side St Johnstone.
