Many wrestling fans question what's in store for Brock Lesnar as he takes on John Cena for the second time. Lesnar won his previous match with Cena for the World Championship belt, which he has been able to keep since.

Fans expect that the 37-year-old WWE star could still win against Cena in their upcoming second match.

However, WWE fans are worried that if Lesnar wins the match against Cena, there might not be other worthy fighter to oppose him in the WWE.

WWE patrons believe that some of the opponents that Lesnar has the possibility of facing may not stand a chance against the WWE World Heavyweight Champion. Among those believed to be lined up to face Lesnar is The Big Show, who, as observers suggest, has become a beatable giant on WWE and a match against the WWE champion will almost certainly bore fans.

Another possible match is against the Undertaker. Fans say this potential match just might hold some excitement, although they do not plan to keep their hopes all the way up as the Undertaker is reportedly set to take the entire year off.

Next is Roman Reigns, who, according to fans, may not be as experienced as Lesnar's opponents need to be. Although Reigns is believed to be physically capable of taking on Lesnar, experience still appears to be the key element in taking the WWE title holder down.

Finally, retired WWE fighter C.M. Punk is being called out by his fans to save WWE from Brock Lesnar. Unfortunately Punk previously stated that he intends to stay retired, but regardless, his fans remain hopeful.
