#4. WWE RAW Superstar Mansoor - 83.33%
Mansoor looked set for greatness in the WWE when he became the winner of the Battle Royale on WWE Super Showdown 2019 in Saudi Arabia. Since then he has quietly started stringing together an impressive win streak in NXT.
From September 20th, 2019, including house shows, Mansoor won 49 matches in a row, in both singles and tag team action, and remained undefeated all the way until his Monday Night RAW debut against Sheamus on May 3rd, which he only lost via DQ.

We're including WWE Main Event as the main roster matches. Mansoor has competed in 12 matches across RAW and Main Event and has won 9 of them, beating the likes of Angel Garza, August Grey, Drew Gulak and Akira Tozawa.
His only two losses came in the aforementioned DQ loss to Sheamus and the recent multi-man Battle Royale that took place on this week's Monday Night RAW.
