Republic of Ireland coach Giovanni Trapattoni is confident he does not need to change 'too much' in the squad.
Trapattoni is preparing for his first friendly as Ireland coach against Serbia on Saturday, having taken on the job earlier this year.
He has been holding a training camp in Portugal ahead of the weekend's game and secured a warm-up win at the start of the week.
After assessing the players at his disposal, Trapattoni is hoping his vast coaching experience will be of benefit during the 2010 World Cup qualifiers, which start in the autumn.
"I have to not change too much their mentality, their play and their quality," Trapattoni told Sky Sports News.
"I have to give them only my experience in the little details when they make mistakes for the naive situations."
Ireland defender Paul McShane has been impressed by the passion that the Italian has brought to the job since replacing Steve Staunton.
McShane said: "He's a very passionate man and you see it in his demeanour around the place.
"The way he holds himself, the way he talks, he is very passionate in his work, so it rubs off on the players."
