#1 Rey Mysterio
Rey Mysterio is another perfect candidate to fight Daniel Bryan, and he certainly deserves to be the next WWE Champion. Mysterio recently made his WWE return on the 1000th episode of SmackDown, and he defeated the US Champion, Shinsuke Nakamura.
Afterwards, he competed at Crown Jewel for the WWE World Cup. Rey Mysterio is a veteran in the ring, and he has been wrestling for a long time.
He signed for WWE in 2002, and he has obtained a lot of success in his long WWE career. He has won numerous titles in WWE, and he is considered to be one of the best high flying wrestlers in WWE history.
Rey Mysterio has won the WWE title thrice, Cruiserweight title thrice, Intercontinental title twice, and the tag team titles four times. He also won the Royal Rumble in 2006.
A feud between Rey Mysterio and Daniel Bryan will be fresh for the WWE Universe. Presently Mysterio is a babyface, and it makes perfect sense to feud with a top heel like Bryan.
