No-one does sporting recluses better than the Socceroos.
For almost 50 years, we've hardly heard a peep from former Australia skipper and 1974 World Cup hero Peter Wilson, who lives in virtual anonymity south of Sydney.
And apart from a brief sighting in the pasta aisle at a Woollies a few years back, ex-Socceroos leader Lucas Neill remains as publicity shy as the Loch Ness Monster since earning the last of his 96 caps in 2013.
Tom Rogic was the latest Socceroo to go MIA, slipping quietly out of Glasgow after helping Celtic FC win last year's Scottish Championship and turning his back on Australia's World Cup qualification bid.
National coach Graham Arnold admitted he was concerned for Rogic's welfare after text messages went unanswered.
Asked if he'd had any contact with the shy midfielder, Celtic's Australian-born manager Ange Postecoglou said: "Has anyone spoken to Tom? No-one spoke to him when he was here for 10 years either, that's Tom.
"I'd be actually more concerned if he was out there talking to people. Leave him alone, he’s fine."
Rogic is a different cat who walks to his own beat, preferably alone.
Not for him an entourage of hangers-on and sycophants pumping up his tyres and trading off his celebrity.
"Tommy plays football because he's good at it and he loves it, but he hates all the other stuff that goes with it," one former Socceroo team member told Yahoo Sport Australia.
"The 90 minutes on the pitch is no problem but he's not into the attention."
That much is clear when you take a quick look at his social media accounts.
Tom Rogic is an enigma on social media
Rogic has been on Twitter since 2013 without posting a single message, attracting 69k followers and following just 47 people and organisations in return, including Cristiano Ronaldo, Virgil van Dijk and LeBron James.
His Instagram posts are few and far between and are usually restricted to shared content.
Rogic spent nine seasons at Celtic and was a firm fan favourite after sticking with the Hoops through thick and thin.
After helping them to the league title and back into the Champions League, most assumed he would stick around for the party to follow.
But talk of a testimonial with all its accompanying media commitments and attention to mark his 10 years at Celtic Park are believed to have spooked Rogic.
Apart from inadvertently photo bombing a fan's snap of One Direction star Louis Tomlinson at Melbourne Airport, he completely disappeared off the radar to parts unknown.
This week's announcement he'd be joining English Championship club West Bromwich Albion on a one-year deal is a surprising and positive development for Australia just two months out from the World Cup.
Socceroos fans are hoping Arnold's next text message to Rogic receives a thumbs up emoji at the very least.
