Mullin suffered a collapsed lung and four broken ribs during the club’s pre-season tour of America and missed Wrexham’s return to the Football League.
Also in the side for Tuesday’s goalless draw at Mansfield Town, Mullin has bagged 81 goals in 102 appearances for the Reds since arriving from Cambridge United in the summer of 2021, and Page confirmed he has been keeping tabs on the 28-year-old.
After announcing his squad, which includes Wrexham-born Owen Beck for the first time as well as Charlie Savage, Page told Wrexham’s official website: “Paul is on standby for the squad. I watched Paul Mullin against Sheffield United last year, and Jack Lester – my coach, who was at Sheffield United at the time – sang his praises.
“We’ve had a few conversations about Paul,so the next step is he’s now on standby and he’s one step away.
“We monitor the Welsh players, and Paul is certainly one we’ve taken note of – and he deserves that. This is the next step of his development.”
The match against Gibraltar is Wales’ first at the world’s oldest international football stadium since playing Trinidad & Tobago in 2019.
Delighted to be back in north Wales, Page added: “It’s massive for us. On behalf of all the players we want to thank the North Walian supporters, who always travel to watch us.
“To come up to Wrexham, and show them that respect, and give them the opportunity to be at home, is just a small price for us to pay [to thank them].
“We’re looking forward to it. It was the home of Welsh football when I was growing up, and I watched many internationals from here when I was younger, and on the TV with Rushy and Mark Hughes. For us to be coming back up here to play again is exciting.”
