Warren Gatland will be in charge of the British and Irish Lions for next year's tour of New Zealand after being named as head coach.
Gatland, 52, will relinquish his duties with Wales for a year before resuming the job he has done since 2007.
New Zealander Gatland will lead the Lions for the second time in his career having masterminded the series win four years ago over Australia.
The Lions have won only one of their 11 series against the All Blacks, in 1971, and the 2017 tourists face a daunting task with a tough itinerary leading to the three-Test series against the world champions.
"It's probably the biggest job in world rugby against the best opposition in world rugby," Gatland said after being unveiled on Wednesday in Edinburgh.
The 10-fixture tour includes five games against Super Rugby opposition and a clash with the Maori, then a three-Test series against the All Blacks.
Gatland, who was also part of Sir Ian McGeechan's coaching team in South Africa seven years ago, is convinced the tourists can prevail against the odds.
"I know from having been in New Zealand recently how much excitement there is ahead of next year," Gatland said.
"For the All Blacks, a Lions series is the ultimate test, but I'm 100 per cent confident that we can go and win in New Zealand.
"The chance to work with the best players from the four Home Nations is a coach's dream and we have some outstanding talent to select from," Gatland said.
Gatland, who has won two Grand Slams with Wales, departs for New Zealand on Thursday to begin plotting the All Blacks' downfall and will be accompanied by tour manager John Spencer.
He confirmed an intention to name his coaching support staff and management team on December 7 for the tour.
"I haven't really had much time to think about that at the moment," he said.
"I think what we've learnt in the last couple of (Lions) tours I've been on is that you want some continuity.
"There is a limited amount of preparation time, so some continuity is important, and I think it is also important that you get some fresh faces and bring some fresh ideas as well.
"I fly out to New Zealand tomorrow to do a reccie in terms of looking at hotels and training venues. I will get a chance to see the All Blacks on Saturday in Hamilton against Argentina, and then next week in Christchurch against South Africa.
"I am incredibly excited. I wouldn't be here if I didn't think we had the ability to go to New Zealand and win."
