In that case, we will see the Swiss Cyborg kickstart an important feud with the WWE Universal Champion on the blue brand.At WrestleMania 37, Cesaro competed in one of the biggest matches of his career. He picked a huge win over The Messiah, and they arguably delivered the best match of the night.Cesaro has recently gained a lot of momentum on WWE SmackDown. In fact, he looked set to challenge Roman Reigns for the title back at the Elimination Chamber PPV.🛸🛸🛸🛸🛸#WrestleMania @WWECesaro pic.twitter.com/I211PYqL9p— WWE (@WWE) April 11, 2021After an excellent win at WrestleMania, Cesaro is once again prepared for the next big step.The Swiss Superman has eight titles to his name in WWE, including the United States and Tag Team Championships across both brands.However, he has never held the world title before. This should give him enough motivation to go after the biggest heel in WWE and his Universal Championship.Even if this feud doesn’t end in Cesaro’s victory, it could still be monumental for his singles run. He is a talented superstar who has been on the sidelines for far too long.After his recent booking, Cesaro deserves a good opportunity in WWE. He can make Roman Reigns look good as a heel without making himself seem like a weak babyface.This storyline has a lot of potential for the creative to explore on WWE SmackDown.
