Formation! The Sasuke Recovery Team

is the episode 110 of the original Naruto anime.

Summary
When Sakura awoke, she informed Izumo and Kotetsu, who told Tsunade of Sasuke's defection. Unable to send higher ranking ninja after Sasuke, Tsunade ordered Shikamaru Nara to assemble a team of genin under his lead to go after Sasuke. He selected Naruto, Neji Hyūga, Chōji Akimichi, and Kiba Inuzuka, and quickly devised the optimal formation for the group. Before they left, Sakura pleaded to Naruto to make sure to bring Sasuke back. Naruto promised to do so, and the group set out.
