Republic of Ireland manager Giovanni Trapattoni insists his team's hopes of Euro 2012 qualification remain very much alive despite Friday's 0-0 home draw against Slovakia.
The Republic dropped two points behind group leaders Russia but Trapattoni believes his team can win in Moscow on Tuesday afternoon.
"I am confident if we play in Moscow like we did this evening," he said.
"We have this game (in Moscow). We can win it. Why not?"
The Republic appeared to be outplayed for long periods by the Slovakians on Friday at the Aviva Stadium but Trapattoni refused to be downhearted.
"The game has been in the balance," insisted the Republic manager.
"In the first half, they were physically superior to us. In the second half, we had two or three chances, (Aiden) McGeady, Robbie Keane and (Simon) Cox.
"In the second half, we deserved to score although they too had a big chance against us on the counter-attack."
Trapattoni claimed that Portuguese referee Pedro Proenca should have awarded the Irish a late penalty for a challenge by Martin Skrtel on Keith Andrews.
"I complained to the referee from my position. I thought it was a penalty," added the Republic boss.
Sean St Ledger was also unhappy with the Portuguese official after receiving a yellow card which rules him out of Tuesday's vital game in Moscow.
"I've not intentionally stuck my leg out. I tried to get out of the way and he's just brandished the yellow card," added St Ledger, who was named man of the match.
"I thought the referee was poor all night, really - indecisive, a lot of bad decisions.
"But that's football. We have to try to get on with it and lift ourselves."
