Giovanni Trapattoni has warned his players to keep their heads in Andorra or risk blowing the chance of Euro 2012 qualification.
"Andorra have a very aggressive mentality. We must remain calm because any reaction could be very dangerous," said Trapattoni.
"The atmosphere in this stadium will be very intense and we have the opportunity to show that we have achieved the right mentality. I don't care about the performance. I'm only interested in the result."
Trapattoni will keep a close eye on events in Slovakia on Friday night and is hoping that Russian involvement in the Champions League could help Ireland's cause.
"Slovakia have quality. Many of the Russians play in the Champions League and maybe they will have another mentality on the night. Maybe they will be tired."
One way or another, Trap will keep his players in the dark about the Slovakia v Russia game which kicks off an hour before Ireland's clash with Andorra.
"They might be conditioned by that result so we will not tell them unless there is a particularly good result ."
