Australia midfielder Jackson Irvine turned heads on day one of the team’s World Cup training camp after arriving wearing a classic Celtic shirt.
The 29-year-old former Hoops youngster, who now captains St Pauli in Germany, turned up in Doha sporting the 1997/98 home jersey with Viduka 36 printed on the back on Sunday.
It comes as the Socceroos prepare for their opening game in Qatar against world champions France next Tuesday.
When asked about the shirt he replied “it’s a classic” and the Socceroos shared it on their official Twitter account saying, “the drip of this kit”.
Irvine spent three years at Celtic between 2012 and 2015 but only made one competitive appearance for the club as he spent the majority of his time in Scotland on loan at Kilmarnock and Ross County.
After four years in England and spells with Burton Albion and Hull City he briefly returned to Scotland to play for Hibernian for six months before signing for St Pauli.
He was handed the armband at the Bundesliga 2 side shortly after and captained the Pirates to a famous derby win over Hamburg earlier this season.
There is a growing Australian contingent at Celtic Park with manager Ange Postecoglou, assistant coach Harry Kewell and Irvine’s international teammate Arron Mooy who is also preparing to take part in the World Cup.
Former Australia forward Mark Viduka played for Celtic for two years between 1998 and 2000 before leaving to sign for Leeds United.
The Scottish Premiership is well represented in the Australia team with players including Hearts midfielder Cammy Devlin, Hibs star Martin Boyle and Scottish-born former Rangers player Jason Cummings.
