Charlie Mulgrew insists he will always make himself available for Scotland.
The Blackburn Rovers defender is the oldest outfield player in the squad at 33 and started Saturday’s 2-1 win over Cyprus at Hampden.
He has 39 caps since making his debut in 2012 and has no plans to step away from international football just yet.
He said: “I’m still only 33, it’s not quite life in the old dog yet. I’ve always said I’ll be there for Scotland as long as they need me.
“I’m happy to play on the right side of defence. It’s different for me but I enjoy it. Scott McKenna is a great prospect and I’m delighted to play alongside him.”
Former Celtic and Aberdeen man Mulgrew, who plays under ex-Hoops boss Tony Mowbray with Rovers, is ready if called upon to face Belgium.
He added: “These are big games but we need to be ready for what they bring.
“They have all sorts of world-class players but these are the guys you want to play against. We’re looking forward to it.”
Scotland’s new boss Steve Clarke started his reign with a victory on Saturday night and he has already made a telling impact on the players.
Mulgrew said: “People say international managers don’t have much time with players but after these double sessions, believe me, he’s had time.
“It’s been really difficult but also really enjoyable. We are lucky to have him and it’ a good start.
“It’s early days but he’s looking top drawer. He keeps things simple. You’d be surprised how often that doesn’t happen. It’s simple and effective.”
