Gary Caldwell is determined to earn himself a regular place in the Celtic side and with it a spot in the Scotland squad.
The defender has been relegated to the bench since the start of the season with boss Gordon Strachan favouring captain Stephen McManus and John Kennedy in central defence.
Scotland take on South Africa on Wednesday at Pittodrie as a warm-up for the Euro 2008 double-header in September against Lithuania at Hampden Park and France in Paris just four days later.
The 25-year-old came on as a substitute for Celtic during their UEFA Champion's League third qualifier at Spartak Moscow on Wednesday and he hopes to make a breakthrough sooner rather than later with some hard work, knowing that his international career is dependent on his club performance.
Working hard"There are a lot of players fighting for positions and I'm one of them," Caldwell said.
"I was unfortunate that I had a wee injury that knocked me back a couple of weeks in pre-season and you lose your place because of that.
"It's up to me to train, fight hard everyday to try to win it back.
"Everyone knows that you've got to be playing at your club to play at international level.
"I understand that and hopefully I can get back in and get back into Alex McLeish's plans as well.
"It's just about working hard and trying to show the manager every day that I should be in his team and hopefully I get the nod soon."
Caldwell hopes he can get back in Strachan's side as early as Sunday's Scottish Premier League clash with Aberdeen at Pittodrie.
"I'm sure that given a chance I can get my place back but I just have to wait my time," he said.
