Yet Steven is dreaming of partnering younger brother Gary at the heart of Scotland's defence as he bids for his first cap in more than three years.
Burnley captain Caldwell was named in George Burley's 23-man squad for next Wednesday's crucial World Cup qualifier in Norway.
Steven Caldwell: "We've both been fortunate enough to play with each other before so it would be tremendous to play alongside him.
"We've never actually played centre-back together.
"I think he played right-back the game that we played together in the qualifier in Moldova so it would be an unbelievable honour and something I look forward to.
"I'm pretty selfish - we all are in football - and I just want to be on the park."
