Any shinobi that knows seals and contracts can defeat Naruto the same way Hashirama defeated Madara. Break the contract seal he has with the kyuubi, rip the 9 tails from his body and he will be weakened.
At this point Naruto would be in a better state of health than Kushina was when it was ripped from her bc she had also just delivered a baby.
Naruto will go to Sage mode which will be tough but can be defeated as he cannot maintain that mode for long. Send attacks to distract him and dodge his until he runs out.
Then he will go to using multi shadow clones. A wide scale ninjutsu like a water rapid, forest cutter wind jutsu, searing migraine fire technique used by Kakazu, or kunai with paper bombs would be ideal to reduce the number of clones.
No doubt rasengan will be used. He will either come straight at you or drop from above with this attack. Dodge or surprise him with a counter attack like Kakashi would.
Without the 9 tails Naruto is not impressive well... sage mode is but other than that he's not impressive. Combine that with his lack of intelligence and well he's basically gonna be ranked right below Jiraiya since he mastered sage mode but is not as smart as Jiraiya.
