#4 Bruno Sammartino
The feud between Vince McMahon and Bruno Sammartino was one that no-one ever expected to be resolved.
The pair were at loggerheads for more than two decades following Sammartino's departure from the company in 1988 until he finally agreed to be brought back into the fold with a Hall of Fame induction in 2013.
Their animosity stemmed from the fact that Sammartino disapproved of the direction McMahon had taken wrestling and was particularly dismayed by what he regarded as distasteful storylines and the unnatural, enhanced physiques sported by many of the promotion's biggest stars.
McMahon, for his part, was enraged by how Sammartino repeatedly rejected any invitations to work for his company again.
Finally, after Triple H intervened and showed Sammartino the current WWE product that the legend approved of, his stance softened and he agreed to meet with McMahon prior to his Hall of Fame induction and the pair became friends.
McMahon and Sammartino remained cordial and continued to work together until the veteran's death earlier this year.
