#1 Sami Zayn
Sami Zayn is not a surprising name here, and he could be a perfect candidate to be the next challenger of Finn Balor. Zayn was sidelined due to injury, but he is expected to return before WrestleMania 35. He could challenge the current Intercontinental Champion after he returns from injury.
Sami Zayn has been an underdog in WWE, although he was a prominent name in NXT. He had some memorable bouts in NXT when he won the NXT title once. In fact, he also won the NXT Superstar of the Year in 2014. However, he failed to replicate the same performance on the main roster. Though Zayn made his main roster debut in 2016, he has not managed to win a title.
Sami Zayn might alter his appalling run on the main roster after he returns from the injury. There is no denying that Zayn is an exceptional performer in the squared circle and he can offer a mind-boggling bout against Finn Balor. Zayn could grab his maiden main roster title if he manages to beat Finn Balor at the Show of Shows.
