Liam Brady believes that Ireland have the players to adapt to a 4-3-3 formation, but says that Robbie Keane would not feature in such a line up.
"If you're going to go to that formation (4-3-3), it would probably mean Robbie wouldn't be in it," Brady told the Irish Times. "I don't think [Giovanni Trapattoni] would be frightened of that at all."
Nevertheless, the former Ireland international says that the Italian tactician prefers the 4-4-2 formation on the grounds that it achieves more favourable results.
"I think what he genuinely believes is that the other formation is better at getting results," added Brady. "And you might argue until the cows come home with him."
He continued: "I was hoping that he might change. I would say the players are there. If he's going to play James McCarthy, it would suit him more in a three.
"I hope he does it because I'm a great supporter of Giovanni as a person, and he's totally dedicated to his job. The players are there for a 4-3-3.
"I thought [McCarthy] should have been in quite a while ago," said Brady. "He's a very good player. We'll see how he gets on in a 4-4-2."
"He’s in a difficult situation, he would know that. He’s vastly experienced and he will know after the disappointment of the Euros, he will have to get off to a good start because he will know it could turn nasty.
"But that’s the life of a manager. No one knows that better than him," concluded Brady.
