5: Pete Dunne
If there is one thing Jericho has been willing to do throughout his career, it is put over up and coming young talent.
Pete Dunne is the WWE's current UK Champion, and the 24-year-old superstar has one of the brightest futures in all of wrestling.
The Birmingham native has already proven he is one of the most capable in-ring performers in the world, putting on match of the year candidates alongside the likes of Tyler Bate and Trent Seven, and his hard-hitting in-ring style could compliment Jericho perfectly.
Outside of that, Dunne is also excellent on the mic and Jericho could no doubt help drag the best out of him in that department.
Jericho has also shown a willingness to help draw a crowd to a promotion, so who knows? maybe we could even see the former Undisputed Champion make a surprise appearance in NXT: UK or Progress.
