This list could be a lot longer.
There have been so many times that a player trades ah club for its crosstown rival or moves from one club to what he considers to be a bigger club and causes a lot of consternation amongst the fans.
Putting together this list was tough to narrow down to 10 but we'll take a look at the top 10 and we'll see who made the list of the biggest traders ever at number 10 David Bentley.
So if you'll remember, the midfielder started at ****nal.
He left ****nal for Blackburn and then when he had Detroit, a chance to move, uh to any club, um from Blackburn.
He moved to Spurs and ****nal and Spurs, obviously a famous rivalry, and it will not be the last time we see it on this list.
He went so far as to say that he was a Spurs fan in the aftermath of the move and ourselves.
Personal fans not happy about that one, Uh, number nine Michael Owen, Liverpool to Manchester United V in Newcastle, this one a little it as a Liverpool fan, I would have put it a lot further down the list, but the backlash was not quite as intense as some of these other ones as we get further down the list.
But Michael Owen, a villain amongst Liverpool fans or many Liverpool fans now having joined match Manchester United, the only thing that lets him off the hook a little bit is the fact is, in the twilight of his career number eight, another Manchester United related move.
Wayne Rooney, Everton to Manchester United.
Obviously, now we think of Wayne Rooney basically synonymous with Manchester United.
But he's a scout, sir.
He's from ever tease.
A boyhood Everton fan played with Everton coming up through the academy and after 77 appearances for Everton, he moved to Manchester United.
Um, obviously a little bit of a rivalry between Liverpool and Manchester in terms of the cities and Wayne Rooney when scoring against Everton, kiss the badge, the Manchester United badge in the face of the Everton faithful and did not endear himself to anyone in that fan base.
Obviously he made a return many years later towards the end of his time in England.
Roberto Baggio comes in at number seven, the the 1994 World Cup, a villain, I guess.
Um, he missed the penalty for Italy, but his move from Fiorentina, his his boyhood club as well to you Aventis sparked a lot of AH of issues in Florence.
He said that he was compelled to make the move, but they did not take that.
Two days of riots broke out in Florence.
50 were injured in the riots, so obviously he makes it further down the list because of the backlash.
Number six mode Johnston and so this name won't be synonymous won't be familiar to many.
But Mo Johnston started as a Celtic player, joined nonce in France for a spell and he was leaving.
Nonce said that he would never play for any other team in Scotland besides Celtic.
And then he joined Rangers and obviously the old firm.
It is a hugely intense uh Darby there in in Scotland, in glass cow and because of the intensity, Mo Johnston had to live in London despite playing in glass cow for fear for his safety in returning Toa glass cow S O.
That move, hugely unpopular, comes in at number six.
Number five Alan Smith, a Leeds again came up through leads played for leads when they were at the at the top of of Europe.
Essentially, they had made a Champions League semi final and then they were relegated famously in the mismanagement.
The mismanagement of the club led to their relegation.
He had kissed the leads badge in front of Manchester United, said he would never join Manchester United and that he joined.
You guessed it, Manchester United Alan Smith earning a place at number five for when leads were at their very lowest number. Four.
It's a tie for me.
Robert Levendosky and Mario Gotze get come in at the number four spot for leaving doorman when they were at the height of their powers to join.
It is one of the biggest rivalries in German football.
Obviously, in recent years, Dorfman and Byron have competed at the highest levels and indeed, after the Champions League final, both these players left doorman in the lurch for Bayern Munich and it was a at cut rates, Um, from what they would have earned if they had moved abroad.
So moving within within the German Bundesliga, really hurting your former boss, Jurgen Klopp, uh, 11 dusky and girls to get their number four spot for that number. Three.
He earned the nickname Cashley because of this move.
****nal to Chelsea, two big rivals.
And at the time it was.
It was a matter of ****nal, who had been a powerhouse at the beginning of the two thousand's.
Chelsea were growing into after the takeover of Abramovich of Chelsea.
He was splashing cash all over Europe.
Ashley Cole was another one, and he forced his move through to a cross town rival in London and went on to win titles with Chelsea.
So number three, the villain Cashley Cole number to another London cross town move.
So Campbell was at Spurs.
He had become a club legend.
He was very important for them.
But he was running down his contract because he knew he had a chance to join a very big club and at the time, Spurs not at the level that they were now making European finals.
But he ran down his contract at Tottenham.
Everyone was thinking, Okay, he's gonna go to Madrid, he's gonna goto Manchester United.
He's gonna go to a team that is gonna be, you know, at a different level.
Basically, then Spurs.
He ran down his contract and joined ****nal on a free, and Tottenham fans have never forgiven him for it.
Signs with the words Judas print not printed on it Where, UH, we're seeing in the stands all over White Hart Lane, his first return as an ****nal player.
So he comes in at number two and the number one biggest trader in world football history.
The Portuguese was such an important player for Barcelona for so many years, and he had the goal and the audacity to join Real Madrid.
Barcelona fans, obviously not happy seeing one of their icons join their arch rivals.
And for many Barcelona fans, it's not just the idea of joining Madrid, it's It's the Catalan versus Castilian Spanish rivalry, and there's so much that goes beyond what happens on the field.
Barcelona fans threw a pig's head at him when he went to take a corner, and they were burning his jersey in the stands during the match, the first match back at the camp, now against between Madrid and Barcelona.
The intensity of that move cannot be matched by any of the on this list, but those are my 10 biggest traders in world football.
I'm sure there are more and you can you
