#4 Sami Zayn
It is surprising that Sami Zayn, who is one of the best in-ring technicians of the world, is yet to win his first championship in WWE. He had won the NXT title but is yet to hold gold on the main roster.
The Canadian Superstar was an integral part of SmackDown Live in 2017-18, the time duration during which he competed in WWE Championship match at the Royal Rumble pay-per-view as well as the Fastlane show of 2018.
Also, he had competed in a WWE Championship Triple Threat match with AJ Styles and Kofi Kingston on a SmackDown episode.
While many fans would be aware of Zayn's WWE Championship matches, very few would know that The Underdog from the Underground has even challenged for the Universal title.
None of Zayn's Universal Championship matches took place on WWE TV but all of them happened at live events where he used to have matches with his buddy and then Universal Champion, Kevin Owens. On some occasions, Seth Rollins also used to be a part of the match involving Owens and Zayn.
