I think that scene is from the pain arc. Where Tsunade was telling them she was going to call Naruto back..Nothing to do with Sakura.
Not 100% sure though
It was after the Garra Rescue Arc. The Elders wanted to keep Naruto in the village because of the Akatsuki situation. Shizune was sweet-talked on the Elders side to persuade Tsunade, but Tsunade refused as they was making him out as a weapon of the Leaf instead of a Leaf Shinobi.
It was....
Before: Rescue Sasuke Arc or formation of Team Yamato was formed.
