The Everton defender believes that it is time for the younger squad member to prove their worth to Giovanni Trapattoni and put in a strong performance against Austria
The 24-year-old, who has recently forced his way into Giovanni Trapattoni's team, believes that he, along with players such as Wigan Athletic midfielder James McCarthy and Sunderland winger James McClean must demonstrate to Trapattoni that they 'belong on the international stage'.
"It's our chance, the younger lads, to step up and show we belong on the international stage," the Everton defender told reporters. "James McCarthy showed on Friday night why he is playing week in, week out in the Premier League.
"James McClean had a fantastic game. We're not that young anymore, 22, 23, 24 – we need to step up and be counted. Robbie Brady is ready and wanting to come in as well."
He continued: "We've always had confidence in our own ability, playing in the Premier League regularly. We just needed a chance to get in and impress the manager."
The former Sligo Rovers full back acknowledged that the Boys in Green were missing the experience of players such as Damien Duff and Richard Dunne, but stressed that it was time for the next generation to stake their claim for a place in the team.
He said: "I know we've lost a number of players from Euro 2012. Richard (Dunne) is injured but would be welcomed back tomorrow.
"[Damien Duff] is a massive player and I'm sure he could still play for Ireland – he is that fit. But this is our chance now," he added.
Looking ahead to tonight's clash with Austria at the Aviva Stadium, Coleman suggested that Ireland could win the game, if they approach it with confidence, while admitting that they would be disappointed if they do not secure three points.
"If we bring confidence from Friday into it, then we can win the game," he said. "They are going well in the group and they scored six goals on Friday (against the Faroe Islands), they'll be well up for it.
"We'll have to be as well prepared as we were for Sweden. It won't be easy, but we'd be disappointed if we didn't win."
