The Italian tactician has revealed that he has belief in his team's ability to get a favourable result against Sweden and Austria in forthcoming qualifiers
The 74-year-old named a provisional 29-man squad ahead of the qualification games which is set to be cut by six players closer to the fixtures. With the Boys in Green needing victories against their Group C rivals, Trapattoni stated that he was aware of his players' capabilities and said that they must take belief from their recent performances in the summer friendlies against England and Spain.
"I have been in this job four years, I know these players," he said. "I know how good they can be. We must be proud of our performances against Spain and England."
In particular, the former Juventus boss singled out Shane Long for praise, proclaiming that the West Bromich Albion striker had the ability to play for "big clubs" such as Serie A side Roma and English Premier League giants Arsenal.
"Marco [Tardelli] and I have spoken about this before. Our players are good enough to play in Italy. For big clubs. [Shane] Long would be great for Roma. Also Arsenal, they know him well."
The provisional squad includes Queens Park Rangers centre back Richard Dunne, who has been recalled after being omitted for the previous game against Wales and Trapattoni hinted that he has plans for the veteran defender to play against Sweden on September 6.
Indeed, the physicality and experience of Sunderland captain John O'Shea along with Dunne appears to have particular importance in Trapattoni's game plan in dealing with Swedish talisman Zlatan Ibrahimovic. "[Dunne's] experience is important," said the Italian tactician. "Sweden have lots of tall players, strong players."
Also included in the provisional panel is injured goalkeeper David Forde, who sat out Millwall's league game away to Sheffield United yesterday and is a doubt for the qualifiers after undergoing surgery. However, Trapattoni explained that he had been in contact with the Championship side's medical team, who assured him that the 33-year-old could make a return to action as soon as next week.
Meanwhile Wolverhampton Wanderers striker Kevin Doyle has once again missed out, but Trapattoni insisted that the door has not been slammed shut on the player, whose progress he continues to follow. "I love Doyle as player," he explained. "We know he scored yesterday for Wolves. We watch him."
Republic of Ireland host Sweden at the Aviva Stadium on September 6 before taking on Austria in Vienna on September 10.
