New Zealand have not lost at Eden Park for 23 years and it will take an exceptional effort, better than last week's performance, for the Lions to topple them this time.
Alun Wyn Jones continues alongside cult-hero Maro Itoje continues at lock.
Gatland has not meddled with his winning back row from last week, with captain Sam Warburton playing alongside Sean O'Brien and Toby Faletau.
"I remember everything", Bath speedster Watson said. Reps: K Owens, J McGrath, K Sinckler, C Lawes, CJ Stander, R Webb, B Te'o, J Nowell.
Tew said: 'The fact is when the northern hemisphere comes to us in July, versus when we go north in November, there is an imbalance - but the revenue we bring in when the Lions tour comes around goes some way to even that out. "We've got the confidence and self-belief to win this Saturday and win the series, so all we ask of them is to be open-minded, not to be surprised by us being in front and good enough to win".
"Individual people make packs, and when you do your individual role in that, you get a complete pack".
"As players we are all feeling pretty chilled out at the moment".
"Saturday would be great to win, but then the preparation goes onto the autumn, the Six Nations, and preparing Wales for the World Cup in 2019".
There's no denying the pace and, on occasion, the result of a Test match owes much a team's ability to play within the referee's interpretation of the game. You have got to try and enjoy it. Good pressure. You've got to get excited about it, it's some of the biggest games of their lives. Now we could have come straight to Auckland, but when you come to New Zealand, so far away, it's one of the most lovely countries in the world.More news: Boston Celtics Pick Jayson Tatum in 2017 NBA Draft
Gatland is persisting with the twin pivot combination of Johnny Sexton and Owen Farrell, which proved effective against an All Blacks team reduced to 14 men when Sonny Bill Williams was sent off early. Joe Moody, 2. Codie Taylor, 3.
It is a move that could be seen as bold given Jordie Barrett's lack of experience at worldwide level, but Fitzpatrick, who was the captain at the 1995 World Cup, has no worries.
"The momentum has shifted since the second Test".
Under Steve Hansen, they have won all 11 matches played in Auckland, and only one of those victories was by a single-figure margin - that came against England in 2014. They have all been through the same emotions as the players.
Tew conceded that there was already expected to be more than 20,000 Lions supporters at Eden Park - 12,000 more than the official allocation - at the 45,000-capacity stadium.
The New Zealand forwards have been in fine form this series, showing they should not be underestimated.
"We know that of the 38,000 that were there last Saturday night, only 8,000 were sold officially to Lions supporters so we can not stop canny Lions supporters getting tickets through our normal systems".
Former Lions halfback Mike Phillips says the tourists are favourites for Saturday's decider and insists the "wounded" All Blacks can be steamrolled.
