Republic of Ireland manager Martin O'Neill says his players will "go for it" when they visit Poland in Sunday's final Euro 2016 qualifier.
O'Neill's side are guaranteed at least a play-off place after beating world champions Germany but a win in Warsaw will secure automatic qualification.
"To beat the world champions is a sensational effort," O'Neill said after Thursday's 1-0 win in Dublin.
"We have reached the play-offs and we can go for it on Sunday now."
While victory against Poland will ensure the Republic reach a third European Championship finals, defeat will mean they would have to qualify through the play-offs.
A draw would leave both Poland and the Republic on 19 points - and as to who would clinch the second automatic place (assuming Germany do not lose to Georgia), with head-to-head records the top tiebreaker:
- A 0-0 draw in Warsaw means Poland go through as they will have scored more away goals in meetings between the two sides.
- A 1-1 draw means the head-to-head records would be identical (as the sides also drew 1-1 in Dublin), but Poland would go through as they have the better goal difference of the two sides.
- A draw of 2-2 or higher would send the Republic of Ireland through as they will have scored more away goals in meetings between the two sides.
The Republic produced a heroic defensive display to condemn Germany to their first competitive defeat since October 2014.
The winning goal came from a wonderful finish by substitute Shane Long.
"The players put in a fantastic effort," added O'Neill.
"We showed bravery and courage. We had to withstand a lot of pressure, which you'd expect, and we did that."
