Peter Osgood, Gianfranco Zola and Didier Drogba share an iconic status at Chelsea Football Club.
They are known for brilliance on the pitch, greatness off it, and for achieving a form of footballing immortality in an iconic moment.
And. Because of that last point, only one other man can be mentioned in the same breath: Branislav Ivanovic.
Those are the only ones to have scored a winning goal in a major European final for the club, and yet many detractors seem to wipe that memory clean when they deposit criticism at the door of Ivanovic.
Nine years after signing for Chelsea, the fullback looks to have reached the end of the road at Stamford Bridge.
With a contract that expires at the season's end, and unable to find a place in Antonio Conte's new 3-4-3 formation, he now looks certain to be off: either in January's transfer window, or failing that in the summer that follows.
Ivanovic's performances have come under legitimate scrutiny for some time, if the truth be told.
He does look to be fading in form as the years clock up: something other defensive greats such as Marcel Desailly, and even now John Terry, came to experience.
But the pointedness of the barbs aimed at a man who never gives less than the best he can is something that is a very new phenomenon in the game.
By having the temerity to be an ageing player of diminishing ability during the social media age, he has picked up an almost unparallelled degree of abuse from those who feel emboldened by the keyboard they like to hide behind.
Some will say copping such flack goes with the territory, and it is true a thick skin is a requirement of the job of footballer these days.
This is something Ivanovic does not seem to possess: contrary to his hard-man Serb image, he is an emotional guy – witness his almost cartoonish crumpling back in 2012 when told, live on television, that he was to miss the Champions League final through suspension.
And that is not the only occasion we have seen raw emotion from a man who wears his heart very much on his sleeve – something which makes the online battering he gets particularly cruel, as well as unseemly for one who has contributed so much.
All of this – the longevity of service, the highs, the bitter lows – seemed very unlikely when he was signed by Avram Grant back in January 2008.
Short of fitness, owing to the long winter closed season he sat out as a Lokomotiv Moscow player, he remained unseen by the public until the following campaign.
The transfer initially looked more a case of Roman Abramovic transferring his ISA, than a proper investment for the team.
But, once installed in the side, he became a versatile mainstay: playing either in the middle, or out on the right of defence.
Having been a rock on the way to Munich 2012, he missed out on that triumph: before his greatest moment came in the consolation prize of the 2013 Europa League – with a late, late header, and some well-earned crossbar straddling after the whistle.
Sources close to the player say he favours a move that will keep him in London.
At 32, both Arsenal and Tottenham would seem unlikely suitors: which would leave either West Ham or Crystal Palace in the Premier League.
Watford and Southampton would also be within commuting distance: but, as a close confidante of the owner, he will surely get a posting he considers favourable.
But, when Ivanovic moves on he will be missed: as a never-say-die dressing room personality, one of the most enduring team players of the Abramovich era, and a true great of recent years.
Many of those so quick to decry his time with the club would do well to remember all that he has achieved – including a starring role in one of Chelsea's all time greatest moments.
