Ireland, with Spurs trio Robbie, Steve Carr and Gary Doherty all in the squad, are one point behind group leaders Switzerland before the make-or-break affair in Basle.
If Ireland win, they are guaranteed a play-off spot, a draw might be enough and then Russia, on the same points as Ireland, come into the equation - they should beat Georgia at home.
"It is a massive game and a must-win," insisted Robbie. "It is one I'm looking forward to."
Any nerves? "No, personally I don't get nerves and just look forward to games and get excited. Like I said, it is going to be a massive game and everything is riding on it.
"We've got a good squad, a good bunch of lads and we would love to turn it around after a bad start for Chrissie and the manager."
Robbie Keane forgets any talk of a draw being enough for Ireland today - he says their Euro 2004 clash in Switzerland is 'must win'.
