1.Andrade

Andrade has been conspicuously missing from television since WWE Super Show-Down. The reason for his absence was his mother's unfortunate passing. Due to his absence, his ongoing feud with Finn Balor over the Intercontinental championship was cut short. His absence has killed the momentum he had built up.
When Andrade returns, he would want to work his way to the top of the card. The most feasible way to do that is to go after the WWE Champion, Kofi Kingston.

The Mexican star is loaded with talent and charisma, he definitely deserves a shot at Kofi's WWE title. Andrade hasn't won championship gold on the main roster. With the help of Zelina Vega, Andrade could target Kofi Kingston just like Samoa Joe did. He could viciously attack Kingston and lay him out, making his message loud and clear.
WWE management is high on Andrade, he has won the hearts of many backstage officials and has rightfully earned an opportunity to challenge for WWE's most prestigious title. Andrade will be a great challenger for Kofi and I certainly wouldn't be surprised if Andrade did defeat him to win the WWE title.
