MARTIN O'Neill believes that David McGoldrick and Cyrus Christie can offer even more than they did during sparkling debuts against the USA.
"McGoldrick has missed all pre-season because of injury," he said. "He's made a contribution which is important. I thought the fellow débutante Cyrus Christie was tremendous.
"I think Christie and McGoldrick, two excellent debuts, are epitomizing what we're trying to do.
"It's important for us to know that if Seamus Coleman got an injury we have Cyrus Christie to come in. He's a lot to live up to in that position, with Coleman normally there, but he had a brilliant debut, really brilliant."
O'Neill (left) also had words of praise for Robbie Brady, another big performer on the night.
"I think Robbie knows himself he has things to improve on as a defender," he added. "He is an excellent footballer. I'm delighted for him."
O'Neill will now hunker down for a four-month wait until Poland in March and his focus is already firmly on that fixture.
"The qualifying games are the most important and everything else is a build-up to them, even including this game," he said.
"We scored four goals and it was nice, and it was nice to regain momentum from Friday night.
"But the most important fixtures, again, are the matches that we have in 2015, so those are important for us. We have seven points on the board."
O'Neill is still feeling pangs of regret from last Friday night in Parkhead but he is happy to end the year with some momentum.
"It was disappointing not to have got something from the game on Friday, but it is not fatal. Regardless of the result on Friday, if we had got a point of out the game, we would have still been looking to try to beat Poland and Scotland. Those next two matches are of vital importance to us."
