in an undisturbed battle the fourth raikage would win against sasuke Uchiha

Rules when fighting a person with the sharingan 1) If it's 1 on 1 you must flee. 2) If it's 2 against 1 then take the back. "You know what "If it's 1 on 1 you must flee" means right?" There is no way you can win"- Granny Chiyo the highly praised shinobi of the hidden sand village. Sasuke because he now possesses Itachi's transplanted eyes he no longer feels the setbacks that the Mangekyou Sharingan tends to give to the user which is steady blindness, and on occasion bleeding from the eyes. It has been stated by Madara Uchiha and Itachi Uchiha, that the only way to acquire the perfect Mangekyou Sharingan is to implant the sharingan eye from a sibling. "Itachi's left Mangekyou possesses the ultimate Genjustsu, then his right Mangekyou contains the ultimate Ninjutsu, The Amateratsu"- Zetsu The references you made are from the fight with Sasuke and Raikage; when Sasuke had already exhausted a majority of his chakra killing Danzo the candidate for the position of the 6th hokage. At that time Sasuke could not have fairly fought with the Raikage because he was already feeling the effects that the Mangekyou Sharingan gives to the user after using Tsukyomi, Amateratsu, and Susanoo in unison. Sasuke was at a disadvantage from the start, his eyes were blurry and have been bleeding all day of course he could not focus on the Raikage's movements. When Sasuke fought Itachi, Zetsu made a remark saying Itachi's sight was getting worse and it was showing when he failed to dodge moves he could easily have dodged in the past. But since my opponent has made his into a fair fighting ground with Sasuke being healthy with full chakra his sight should drastically improve. But onto Raikage's abilities, Raikage's abilities are a mixture of very advanced Taijutsu(hand to hand combat) and joining that with a lightning element. Raikages range is not long distance which does not play into his favor. Raikage's attacks have to be in close range and Sasuke just needs to make eye contact to trap the 4th raikage in the ultimate Genjutsu: Tsukyomi. The Raikage's personality is not calm, so he will continuously rush because his pride forces him to believe that he is always stronger which is shown when he gave up his left arm just to try to land a hit on Sasuke when they fought in the manga. To the main point a fresh Sasuke with the transplanted Mangekyou sharingan in his possession makes Sasuke untouchable the strain on his body is no longer existent, the price of his brothers life for unspeakable power. Sasuke has multiple defense mechanisms which include the Amaterasu shield, and Susanoo. Raikage will have to bulldoze his way through all these fresh defensive mechanisms while keeping all his body parts intact. Amateratsu will burn anything it touches. 4th Raikage's abilities deals too much with getting his hands on the opponent it is just a matter of time before Sasuke either stares at him in the face and traps in Tsukyomi or Raikage burns off his hand again trying to bust through that defense. Raikage cannot run forever around Sasuke's defenses. Sasuke has the sharingan and copying Taijustsu and lighting based jutsu's are his specialty, its only a matter of time before the sharingan gets used to the movements just like the fight with Haku. Tsukyomi can only be broken by a user with the sharingan or a person fixing the disrupted flow of chakra. Since Raikage does not possess either the sharingan and they are both alone in this fight, Raikage will be trapped in a seemingly endless genjutsu (Tsukyoumi alters the perception of time space for the person its being casted on) because nobody is there to disrupt the Chakra flow. Raikage will not be able to break the genjutsu on his own therefore making Sasuke the winner.
