Ciaran Clark is hoping to grasp his opportunity to impress Republic of Ireland coach Giovanni Trapattoni in the friendly against Uruguay.
Aston Villa youngster Clark will start at left-back against the World Cup semi-finalists and will win his second cap after making his debut against Wales last month.
The 21-year-old is among those in contention to replace the suspended Richard Dunne at centre-half for June's Euro 2012 qualifier in Macedonia, and will also have games in May against Northern Ireland and Scotland to catch Trapattoni's eye.
Clark is aware there is plenty of competition for a spot in the starting line-up and he will be doing his utmost to impress against Uruguay.
"I would like to put in a good performance and it is a good chance for me from now until the end of the season to show what I can do," said Clark.
"There are a lot of good players in the squad and everyone will be fighting for places in the team because everyone wants to play.
"But we have got Tuesday night's game to concentrate on, then there are the Nations Cup games which will give players a chance to impress."
Trapattoni could have asked Clark to play alongside Darren O'Dea in the middle, but decided to select him in the left-back spot, where he has performed creditably for his club in recent times.
The Italian said: "Ciaran Clark is still quite young and at times, it is dangerous in that position.
"He is young and young players are always anxious to get on the ball, and that's the danger.
"If you make a mistake in the box, it's a goal. With a mistake near the touchline, it's possible to recover."
