John Cena is one of the biggest names in wrestling history, and the WWE Universe is preparing for his return to Raw on Memorial Day. Cena underwent shoulder surgery in January.

Wrestling fans have mixed emotions about Cena’s return. On one hand, he is a top star, and the business is always better when he is on the card. On the other hand, his character has been stale for years, and fans have grown tired of his babyface gimmick.

Regardless of how Cena is handled when he returns to the ring, here are the top potential feuds when he returns from shoulder surgery on Memorial Day.

Rusev

Rusev was one of the hottest Superstars in WWE after making his debut in 2014, but he ran into the unstoppable force known as Cena. Like most wrestlers who are built as top heels in WWE, Rusev was fed to Cena and faded into obscurity thanks to terrible booking.

With Rusev now the No. 1 contender for the United States Championship, Kalisto should be on upset alert. Cena has a history with Rusev and the U.S. title, so the possibility of WWE Creative revisiting a previous feud instead of coming up with something new and unique is high.

There is no question that the original feud between Cena and Rusev for the U.S. title had a strong start, but the eventual victories by Cena stopped any momentum Rusev built in its tracks. Now that WWE is building Rusev up once again, Cena beating him for the title once more would not be hard to believe.

Kalisto has done nothing with the title since he won it—not his fault, blame WWE Creative—and Rusev would regain some credibility by winning the belt. Unfortunately, Rusev’s championship victory could be all about giving the championship right back to Cena.
