Nemanja Vidic is considered by many to be the greatest defender the Premier League has ever seen.
The Serbian spent nine seasons at Manchester United, helping them to win five league titles, three League Cups, five Community Shields, a Club World Cup and a Champions League.
He formed a formidable partnership with Rio Ferdinand and was almost unbeatable.
Or was he?
Since Virgil van Dijk’s emergence as the world’s best defender, Liverpool fans and Manchester United fans have been arguing over who was better - Van Dijk or Vidic?
Actually, rather than concentrate on their own player and explain why they're better, they usually focus on putting the other one down.
And that’s happened once again with one Liverpool fan creating a thread that tries to prove that Vidic is “the most overrated defender in Premier League history.”
It begins: “Nemanja Vidic, always on the floor. A thread exposing the most overrated defender in Premier League history.”
What follows are 15 clips of Vidic - almost always on the floor - as he makes a mistake that usually ends in United conceding a goal.
Here are some of the best clips:
Of course, selecting a few short clips from an entire career isn’t exactly fair but it will put doubts in fans’ minds over just how good Vidic was.
It probably isn’t surprising that Liverpool fans are keen to question Vidic’s ability.
The centre-back was sent off a total of four times in battles against Liverpool with Fernando Torres, in particular, causing him all sorts of problems.
Vidic said that playing at Anfield was always difficult - but he loved it.
"To go away to play there, at Anfield, as a Man United player, I think it's the most difficult place," Vidic revealed.
"Their fans are on top of you, they're very close to the pitch so it's difficult.
"I loved it. That's why I got two red cards there! I enjoyed it too much!"
