Rugby great Brian O'Driscoll has warned his Lions teammates that a series victory in Australia is crucial for the Lions' future.
It has been 16 years since a Lions tour returned home victorious after near misses against Australia in 2001 and South Africa 2009 and a series whitewash in New Zealand in 2005.
While the Springboks prevailed 2-1 four years ago, it was an epic series that reached its high point with a titanic second test that proved there is plenty of mileage left in the Lions.
But O'Driscoll - who was also on those last three tours - insists they cannot afford to lose again when they face the Wallabies in Brisbane, Melbourne and Sydney in June and July.
"It's really important to win this series," the Ireland centre said.
