Giovanni Trapattoni is confident his Republic of Ireland side will go from strength to strength after tasting victory for the first time as manager on Monday evening.
Ireland defeated Portuguese minnows Lagos 3-1 at the Estadio Municipal to boost confidence ahead of the friendlies against Serbia and Colombia.
Glenn Whelan opened the scoring with a well-struck volley and Darren Potter broke from halfway and chipped goalkeeper Toco to make it 2-0.
Lagos pulled one back through Marco Carmo before Andy Keogh clinched the win for Ireland after an excellent Damien Duff cross.
The scoreline could have been even more convincing had it not been for the woodwork and the home keeper, but Trapattoni expects the goals to come if Ireland continue to carve out openings.
"We hit the post twice and their goalkeeper made two or three saves in the first couple of minutes," said Trapattoni.
"What is important is that we created chances. As long as we continue to create chances, we will eventually start to take them.
"That's football. Sometimes, the ball hits the post or the goalkeeper saves it. That's football.
"The important thing is to get to the point where we are getting shots in on goal.
"Scoring four, five or six goals was not important; for me, creating chances was the most important thing."
Manchester-born Kieren Westwood, a late addition to the squad, came on as a second-half substitute and Trapattoni has defended his decision to call up the Carlisle goalkeeper.
Bohemians keeper Brian Murphy had suggested Trapattoni look closer to home, but the Italian believes it was right to give Westwood a chance.
He explained: "I did not know him (Westwood), but our scouts told me he played in the (League One play-off) semi-final against Leeds and played two or three important games.
"We are looking at the young players. We have to look at all the possibilities."
