Preparations on track for Under-17 UEFA Elite qualifiers
Sean McCaffrey's side will also face Finland on Sunday and Austria next Wednesday hoping to win the group and advance to the European Championship finals in Liechtenstein in May.
Only the victor of each of the seven groups is guaranteed a place at the showpiece though following the withdrawal of tournament hosts Liechtenstein there will now be an additional place for the best second-placed team from across the pools.
McCaffrey is delighted to have all of his originally selected squad with him in Greece as they plot a pathway to the UEFA finals.
The 18-player panel arrived at their base in Greece on Monday night and held their first training workout on Tuesday. Wednesday saw them undertake a double-session and McCaffrey is delighted with the desire and commitment demonstrated thus far by his charges.
"The players are in very positive mood about the task ahead in these three matches and their concentration levels in training have been first-class," he said.
"I'm more than happy with the preparations this week. The hotel and training facilities are excellent and we've had no withdrawals from the squad, a major plus going into the first match."
David Murphy (knee), Carl McHugh and Michael Barker (both ankle) took only a limited role in Wednesday's training session on medical advice but are expected to be fit for Friday.
McCaffrey said: "Our physiotherapist Philip Phelan and Team Doctor John Chute have been working this week to heal any knocks experienced by the players and I'm thankful for their assistance in ensuring the squad are in the right condition."
The Irish boss explained that he expects Greece to go all-out for victory in their duel at the Kato Achaia Municipal Stadium on Friday.
He said: "Greece are a well-organised side with a tremendous work ethic about them. They may favour the first-half turning into a battle but once we match them for hunger and, most importantly, discipline, I'd be confident that our technically astute players can cause their defence trouble.
"It's vital that we retain possession. I'm glad that the game is being played in the morning-time, as the heat is unlikely to be a factor, but we need to work to our strength which is getting the ball moving and having a go at them in attack."
