Cap, Black Widow, WS, Falcon and Hawkeye are completly out of place here. Quicksilver is just slow compared to Supes and Ant man is only a very durable insect against him. So the fight is more or less Superman vs Thor, Iron Man, Hulk, Vision and Scarlet Witch. The only way the Avengers can win, is by attacking him all together at the same time and we dont even know if thats enough. Perhabs Scarlet witch can weaken him via her mind controling powers, if she gets close enough, but I dont think she would. Furthermore, she is a glass canon and useless in close distance or unprotected.
The fight: Thor, Hulk, Iron Man and Vision attack Supes directly and first overwhelm him, until he fights back. He flies in the air and throws Thor and Hulk into some buildings, while ripping appart Tonys armor. Vision attacks him with his energy beam and Supes uses his heat blast, while throwing Iron Man to the ground. The full blast overwhelms Vision, but before Supes can punch him, Thor throws his hammer at him and Hawkeye attacks him with some explosive arrows. The attacks does nothing, but buys enough time for the Hulk to jump, grap him and throw him at the ground. Scarlet witch throws some cars at him, Thor uses his lightning, Hawkeye his arrows, Vision his energy beam and Iron Man his repulsor blast. But now he is realy angry and directly attacks the hulk, with his superspeed and flies with him through multiple buildings (The Hulk is probaly KO after this). Thor throws his hammer at him, but Supes just punches it away and punches him throgh multiple buildings. Tonys suit is quickly dismantelt and Veronica is destroyed by his heat blast. Quicksilver trys his luck, but Supes easily dodges his attacks and throws him away. Now Vision attacks him and through his density manipulation he can avoid all of Supes attacks, but at last supes heat blast brings him to the ground. He ignores the rest, perhabs he destroys WW arm, Falcons wings or Hawkeyes bow and flies away.
