Ireland boss Giovanni Trapattoni was pleased with his side's fearless attitude as they held England to a 1-1 draw on Wednesday evening.
The visitors went ahead through a Shane Long strike before Frank Lampard levelled matters for the Three Lions.
Trapattoni insists Ireland will grow following the draw against one of their fiercest rivals.
"England are one of the strongest three, four or five countries in the world," said Republic boss Giovanni Trapattoni.
"I look at my group, and three or four are young. They need experience. Only against a great team and great players can they grow.
"I am happy from what I saw: James McCarthy, Seamus Coleman. Shane Long was clearly the best on the pitch.
"I asked the players to show we can play without fear. I know what this result meant because I saw they were a bit tense in the dressing room.
"I didn't want to put more pressure on them. I wanted to give them trust and confidence. They took my advice and accepted my message.
"The next friendly game against Spain will be another great opportunity."
