Zabuza vs Beginning of Shippuden Naruto and Sakura

Round 1:

Zabuza from the Land of Waves arc vs Naruto and Sakura as they are during the bell test.

Knowledge: They all have knowledge from their previous encounters, plus Zabuza knows enough about Sakura's super strength to not try and tank a punch.

Location: Where Zabuza and Team 7 had their first fight.

Naruto can't use any of Kurama's chakra.

Round 2:

If you think the team takes the first round, Haku from the Land of Waves arc helps Zabuza out

Round 3: Haku helps Zabuza but Naruto can access the same amount of Kurama's chakra as he did against Haku in part 1
