SHAUN Maloney reckons the presence of one man alone will be enough to make the Republic of Ireland a tougher nut to crack at the Aviva Stadium on Saturday than they were back at Celtic Park in November - his old Wigan team-mate James McCarthy.

Martin O'Neill's side were actually deprived of their two first choice screening central midfielders, McCarthy and Glenn Whelan of Stoke City, due to injury when Maloney's spectacular late goal gave Scotland a narrow but deserved win late last year, but the Chicago Fire player knows the involvement of the 24-year-old Everton midfielder is capable of altering the dynamic for the return leg in Dublin. Once again, the Scottish-born former Hamilton Accies player - whose watchful first-half display helped shut out England in last weekend's international friendly - goes into the summer at the centre of transfer attention involving some of the biggest clubs in European football.

"It will make a big difference to them that he's available," said Maloney of the man who cost £13m when he swapped the DW Stadium for Goodison Park. "I was lucky enough to play with him for a couple of seasons at Wigan and he's had another excellent season at Everton. I'm sure they'd hope to keep him.

"I can't speak too highly of him, he could go to the top of the Premiership if he kicks on again," the Scot added. "He's brilliant at winning the ball back and when his team lose possession his pace to get back is excellent. I watched him against Manchester United recently where he showed that pace going forward. He'll be a big player for the Republic of Ireland."

Maloney has emerged as a key player for Scotland under Gordon Strachan, scoring four goals to boost the campaign to qualify for a major finals for the first time in 18 years. It is a tally which might have been five were it not for an effort against Georgia which was credited to an own goal by Akaki Khubutia. His strike at Parkhead came from a specially orchestrated set piece routine from a corner kick, but he reckons the Republic of Ireland will have done their homework this time.

"I can't see anything like that working again," he said. "Teams are aware of what other teams have done previously because there's so much video footage available now."
