Warren Gatland will bid to make history when the Lions take on South Africa in 2021.
He's attempting a feat not even Sir Ian McGeechan could manage by becoming the first coach of the cream of British and Irish rugby not to lose a Test series against any of the three major southern hemisphere superpowers.
Gatland's 2013 Lions conquered Australia 2-1 while the class of 2017 shocked most of the rugby world by drawing its series with New Zealand.
Scotsman McGeechan presided over glory against Australia and South Africa but his 1993 Lions went down 2-1 to the All Blacks.
Can Gatland make history? WalesOnline Rugby Correspondent Andy Howell picks his Lions team as the World Cup reaches its conclusion.
15 Liam Williams (Wales)
Scotland's Stuart Hogg didn't fire at the World Cup and is a player who flatters to deceive while England's Elliot Daly has been found wanting defensively at times.
Irish veteran Rob Kearney, who was the Lions Test full-back after Wales' Lee Byrne was injured in South Africa, had a decent tournament but Williams remains the best of the crop.
14 Anthony Watson (England)
Like Williams, Watson was a Lions starter against the All Blacks two years ago and I can't see any reason for that to change on the right wing with George North a frustrating figure and disappointment in recent times.
13 Jonathan Davies (Wales)
A knee injury meant it's been a difficult tournament for the 2013 and 2017 Lions star but a moment of magic against Fiji highlighted why he's still the best outside-centre in Britain and Ireland despite English rugby's obsession with Manu Tuilagi.
12 Owen Farrell (England)
Partnered Davies in the centre during the second and third Tests against the All Blacks and would be a strong favourite to be Gatland's Lions captain because he's almost certainly assured of a starting spot against South Africa.
11 Josh Adams (Wales)
The World Cup's leading try-scorer with six following the semi-finals, which is no mean feat when Wales aren't exactly known for creativity and spreading the ball wide.
10 Gareth Anscombe (Wales)
This selection may surprise a few but Lions' 2013 and 2017 play-maker Johnny Sexton is a busted flush as injuries and time catch up with him.
Farrell could be picked at outside-half while his England teammate George Ford has exceeded expectations recently.
But it can be argued, especially if surrounded by quality players, Anscombe is more creative than either with his injury-induced loss having been a hammer-blow to Wales' bid for World Cup glory.
9 Tomos Williams (Wales)
England supporters would be crying foul at the absence of Ben Youngs but he really hasn't cut it on past Lions tours.
Conor Murray's best days seem behind him while the prodigiously talented Williams is the future with an all-round game which could be sensational behind a Lions pack.
1 Mako Vunipola (England)
Inexplicably lost by Wales to England after being brought up near Pontypool, and cementing his status as the best loose-head prop in the world with an astonishing work-rate and a highly skilled game.
2 Jamie George (England)
Wales' Ken Owens has pushed hard at the World Cup but he again has to play second-fiddle to the outstanding hooker who kept him out of Gatland's Lions starting team in New Zealand.
3 Kyle Sinkler (England)
Tadhg Furlong was a rarity, an Ireland player who did show glimpses of his ability at the World Cup, but Sinckler has come on leaps and bounds since the last Lions tour.
Yes, he can be a hot-head but is the type of passionate player you want on your team. But it's not just that, for Sinckler is heck of a tighthead prop who will only get better.
4 James Ryan (Ireland)
What no Alun Wyn Jones? I'd argue Jake Ball was Wales' best lock at the World Cup while Courtney Lawes hasn't put a foot wrong.
But the one Irish player who came out of the tournament with real credit was James Ryan, who is being spoken about as being better than a certain Paul O'Connell and is the epitome of the modern lock.
5 Maro Itoje (England)
His on-field antics and celebrations when an opponent makes a mistake anger me but the 2017 Lion is, in my opinion, the best lock in the business and perhaps rugby's finest forward.
6: Sam Underhill (England)
The Bridgend RFC and Ospreys product's mentor is none other than Lions and England World Cup winning back-row great Richard Hill.
And Underhill is a chip off the old block, able to play on either flank, is a shuddering defender who terrorises opponents and never stops working.
7 Justin Tipuric (Wales)
Underhill's back-row partner Tom Curry is a huge talent, as is Wales' Aaron Wainwright while Josh Navidi never lets anybody down.
But Tipuric's stats from the World Cup are stellar with Hill's former England and Lions teammate Laurence Dallaglio saying the Wales flanker would be "eulogised" if he was a New Zealander.
8 Taulupe Faletau (Wales)
English die-hards will be up in arms at Faletau being picked ahead of Billy Vunipola while CJ Stander gave it a shot for Ireland in Japan.
But Faletau, even though he's rarely been seen on the international stage since starring for the 2017 Lions because of frustrating injuries, has more strings to his bow and is an exceptional player who brings an extra dimension.
