Kevin Foley, Sean St Ledger, Eddie Nolan, Liam Lawrence and Leon Best were in the starting XI at Craven Cottage, then Keiren Westwood then came on at the break for his first appearance.

Trapattoni's men fell behind to Michael Enemaro's opener before Robbie Keane grabbed the leveller before the break, with Ireland's inexperienced players seeing out the draw.

"I am very happy with them all, though," the coach said. "We wanted to look at the performance and personality of the new players, and it was important to check on other players for the future.

"The first half was very good game and the performance was strong, too."

Foley, however, picked up a knock and will be assessed on Monday, while Darron Gibson has had a scan on a thigh problem.

It was Foley who was slightly at fault for Enemaro's goal as he was beaten to the ball on the half-hour mark.

Keane then finished off a slick move eight minutes later.

"It was a very good goal and a good moment for Robbie," Trapattoni said. "I saw Robbie play two weeks ago and he is currently in a good period.

"His morale is good and he plays for the team - sometimes as a playmaker, sometimes scoring goals. It's very important for Ireland and he gives time to the rest of the players, which is important for us as well.

"He linked up well with Leon Best. We need players who play up front and Robbie is playing a bit between the strikers and the midfield."

Overall, Trapattoni felt his side had done well.

"It was very interesting - in their performance and their personality against a strong team, not just in Africa, but the whole world," he added.

"They play in good European countries and leagues. They are fast and play the ball well.

"We had them only a few days to learn our system - they have their own systems at their clubs. I have to look at our system as well and see how they fit into that."

Nigeria coach Shaibu Amodu did not appear for his post-match media duties. One banner in the crowd demanding his sacking resulted in a scuffle between fans and stewards.
