#7 Brock Lesnar vs Bobby Lashley
Brock Lesnar will return to the WWE in January at the Royal Rumble when he faces off against Braun Strowman for the Universal title. It is quite likely that the Monster Among Men will win the title at the PPV, which will be his first singles title on the main roster.
Lesnar is most likely going to the UFC to face off against Daniel Cormier, and is currently under USADA's testing pool, and it seems like he will be available for fewer days in the WWE.
One match WWE fans have been waiting for years is a battle between two monsters in the WWE and in MMA: Lesnar vs Lashley. This match-up has got to happen soon, and 2019 could be the year that this huge match takes place.
A match between these two behemoths deserves the grandest stage of them all - WrestleMania 35!
