Tommy Bowe insists Ireland's Lions contingent are desperate to avenge the agonising Test series defeat by South Africa.
RBS 6 Nations Grand Slam winners Ireland conclude their autumn campaign with an eagerly-anticipated showdown against the world and Tri-Nations champions at Croke Park tomorrow.
Billed as 'battle of the hemispheres', the contest has been given an extra dimension by events this summer which saw 10 Irishmen capped by the Lions. All but one of them - the injured Luke Fitzgerald - will be involved tomorrow.
The Springboks edged an epic series 2-1 and Bowe, who started all three Tests, admits the heartache of losing will drive Ireland on tomorrow.
"I really enjoyed the summer with the Lions. It's a rare opportunity to get as a player," said the Ospreys winger.
"There's a big feeling of loss after leaving behind the Test series - there's huge disappointment there.
"This is a chance for us to get our own back so it's up to us to put in a big performance.
"The match has been billed as the best of the northern against the best of the southern hemisphere and has been built up over the last couple of weeks.
"For us to finish our season unbeaten will be huge. I've no doubt South Africa are very worried about this Test.
"The Australians and a lot of the southern hemisphere teams coming here said that we are the team they want to play against."
Ireland began their autumn series by drawing 20-20 with Australia and went on to blow away any lingering cobwebs by thumping an under-strength Fiji 41-6.
South Africa's first visit to Croke Park begins a day of fixtures that could see the northern hemisphere end November on level terms with the Tri-Nations giants.
Wales host Australia and France face the All Blacks - two very winnable games for RBS 6 Nations rivals with positive results leaving the total at five wins apiece with one draw.
But more importantly than striking a blow for European rugby, victory over the Springboks would confirm Ireland as a genuine force on the world stage.
