1). Dolph Ziggler
We have heard this name so many times. He debuted a long way back and since has been one of the most talented wrestler in WWE roster. He has held the World Heavyweight Championship, Inter-continental Championship, U.S Championship and has also won Money in The Bank. He has been the lone survivor of two Survivor Series Elimination Matches in 2012 and 2014.
Despite being so successful, he has never been counted as a top star of WWE. He has never received the push he deserved. When he won the Survivor Series Elimination Match in 2014 almost single handedly, we felt that this is his time but WWE pushed him back to promote other wrestlers and since then, he has just been a mid-card wrestler.
WWE needs to get him to top again, he has the talent to be in the main event wrestlers category. He can feud with AJ Styles or Roman Reigns who are already in the main event category. This will help him to reach the main event.
