Conor Masterson is backing the Republic of Ireland's belief in themselves to fuel their bid for a first  trip to the finals of the European Under-21s Championships.

Ireland travel to Iceland on Tuesday still sitting at the top of Group 1 following a 0-0 draw with Italy at Tallaght Stadium on Thursday evening, a game in which they played the final 26 minutes with 10 men following Troy Parrott's dismissal.

They will run out at Vikingsvollur in Reykjavik to face a side four points adrift of them having played a game fewer, but which was routed 5-0 in Sweden - where the Republic won 3-1 last month - on Saturday.

QPR defender Masterson said: "We believe in ourselves and you see it by the way we're playing.

"Against Sweden, we were the underdogs going into that game but we didn't think that. We believed in ourselves, went out there and showed everyone in this group what we can do."

Ireland, who are seeded fourth in the group, won their opening three games and the point with which they emerged from the Italy clash has added to that platform.

However, they will be without the suspended Parrott and the injured Jonathan Afolabi in Iceland, while a third striker, Brighton's Aaron Connolly, is not available to manager Stephen Kenny after being called into Mick McCarthy's senior squad for the Euro 2020 qualifiers against Georgia and Switzerland.

Connolly's loss in particular is a blow, but his elevation is a source of encouragement to the players he has left behind.

West Ham midfielder Conor Coventry said: "I've played with Aaron since he was 16. I know him well. I know the talent he has and I'm just delighted for him.

"Of course, it shows the rest of us that if we work hard, we can get to where we want to go to and we can make it."

Bohemians winger Danny Grant and Ipswich striker Aaron Drinan, currently on loan with Swedish side GAIS Gothenburg, have been drafted in as replacements for Parrott and Afolabi.
