Sasuke not only was able to defeat Naruto, but Sasuke is smarter when fighting and has مزید diverse jutsus is stronger and is faster, he has full control over his curse mark now, so the fight should be easier for Sasuke, Naruto isnt a custom to Sage mode yat nor can he fully contol the demon لومڑی but his jutsus are all close range so if the fight is long range Sasuke would easily win but if its close range it might be close!!!!
