Okay people who are saying that we're complaining about Naruto being captured is dumb, I'm going to assume that you as well as LemonSage didn't do your research on what sage mode does and just assumed it was just a power boost. Sage mode enhances the user's strength, speed, reflexes, perception, and durability. It also let's them use the natural chakra around them to give them sensory abilities. They can also sense attacks coming EVEN IF THEY CAN'T SEE THEM. IN OTHER WORDS NARUTO WOULD HAVE FELT SORA'S ATTACK COMING.
It isn't that most of us are mad that Naruto was caught by surprise. It's that he shouldn't have been while in sage mode. It was stupid when Mito was smacking him around then, just like it was stupid now.
There's a reason Hishirama was beating Madara despite Madara having EMS. He had SAGE MODE.

No offense but your reasoning is flawed. There is a difference between sensing an attack, and reacting to it, and as Naruto already just reacted to the arrival of a new threat by putting himself between it and Sora. It left him open to attack. Furthermore there is a difference between facing someone in a one on one battle, and being maneuvered into a back attack. Also Hishirama also had his wood release as well, so it wasn't just that he could become a sage that he could go to to toe with Madara.
Ultimately they used his nature against him to maneuver him into a position where they could strike quickly because they were aware of how dangerous he was. Just saying but he was in sage mode, so can't be beaten by people who outthink him is nonsense. Again there is a difference from sensing a attack, and reacting to it. Not to mention sensing something when you are directing your focus towards someone you perceive to be a bigger threat in the moment.
