Irish number two says his Italian colleague is 'strong'...
Trapattoni was admitted to Dublin's Mater Hospital earlier this morning suffering from vomiting and nausea, which has been attributed to the coach eating shellfish.
His assistant Tardelli told reporters at this morning's press conference: "He is strong so maybe tomorrow he will be in the dugout."
The Irish team doctor Alan Byrne took the veteran coach to hospital in the early hours after he began vomiting.
"He is in a stable condition and undergoing some tests this morning. Assistant manager, Marco Tardelli will take charge of the squad today for training, allowing Giovanni to rest throughout the day," Byrne said in an FAI statement.
Tardelli was able to confirm most of the starting line-up but there is still concern over a couple of players. Richard Dunne is a doubt and Kevin Doyle will be replaced by Cillian Sheridan if he does not win his fitness battle.
As expected Robbie Keane will captain the side as he wins his 100th cap. Ironically, the Spurs man also won his first full cap against Argentina in 1998. He is the country's top scorer with 43 goals.
Republic of Ireland starting XI to face Argentina: Given, Kilbane, O'Shea, McShane, Dunne (if fit), Green, Andrews, Lawrence, Duff, Keane, Doyle/Sheridan
