#4 Seth Rollins vs. Chris Jericho (WWE SummerSlam 2018)
Despite appearing in New Japan Pro Wrestling, Chris Jericho was still a part of WWE in 2018. He made a couple of appearances for the company, including as the 50th entrant in the Greatest Royal Rumble Match. Following his IWGP Intercontinental Championship victory over Tetsuya Naito in June, Jericho had an ambitious pitch lined up for SummerSlam.
He called Vince McMahon with the idea of having a cross-promotional Intercontinental Champion vs. Champion match at SummerSlam, between himself and Seth Rollins. This would have been a monumental occurring, even if it would have ended in a disqualification.

However, despite initially garnering a little interest, Jericho never heard back from WWE. This unique storyline would have created an immense amount of buzz among WWE fans, similar to the reaction to Jericho's emergence in New Japan. Rollins ended up losing his Intercontinental Title to Dolph Ziggler, eventually winning it back in the opening match of SummerSlam.
Chris Jericho has not returned to WWE since, wrestling a few more matches with New Japan and eventually signing with All Elite Wrestling, where he has continued the tremendous evolution of his character. Take a look at his incredible career so far.
