The big rivalry between Chelsea and Tottenham Hotspur has proved to be no obstacle for some of these players who have strutted their stuff at both Stamford Bridge and White Hart Lane.
There is only 15 miles, give or take, separating two of London's biggest clubs and it has long been one of the must-see fixtures in English football, with no quarter given and none asked as we've played out some thrilling matches over the years.
Clearly there's no love lost when it comes to Chelsea and Tottenham, but that hasn't deterred a number of big-name stars from plying their trade in both SW6 and N17 during their career, including some who can claim legendary status at one club or the other.
Our second appearance in an FA Cup final came in 1967, when the Blues were managed by Tommy Docherty – himself a former player at another rival of the two clubs, Arsenal – and we came up against Spurs. It was a rare occasion when the Lilywhites got the better of us on the biggest stage, and helping their cause were two men who had been huge favourites at the Bridge.
Jimmy Greaves became the youngest player to reach 100 English top-flight goals after he came up through the youth system at Chelsea, while Terry Venables was another to come off that conveyor belt a few years later, becoming the captain of Doc's Diamonds and displaying one of the brightest football brains in the country, which would later see him become an excellent manager.
To the chagrin of Blues fans, and no doubt Docherty himself, both went on to enjoy successful spells over in north London, with the duo helping Spurs get one over on us at Wembley Stadium as our wait for an FA Cup triumph dragged on.
Gustavo Poyet was part of a Chelsea cup-winning side many years later, finishing as the competition's top scorer in 2000 when we lifted the trophy in the last final held at the old Wembley. The Uruguayan was our goalscoring No8 before the arrival of Frank Lampard, netting at an average of one every three games, establishing himself as a popular figure at the Bridge.
However, when Gus' time in west London came to an end, he made the decision to join Spurs, where he failed to add to his trophy collection despite playing his part in a League Cup semi-final win over the Blues. He even went back to White Hart Lane a few years later to work as assistant manager to Juande Ramos.
Gordon Durie is another who'd banged in the goals regularly for Chelsea in the Eighties, playing his part in helping the club earn promotion from Division Two in 1988/89, but the Scot tainted his reputation around these parts for ever more when he declared he was homesick and wanted to move closer to his family. In his defence, Tottenham is closer to Scotland than Chelsea, but still...
One of the highlights of that famous promotion campaign under the tutelage of Bobby Campbell had been provided by Graham Roberts, a hard-as-nails centre-half who took on the captain's armband and scored penalty after penalty as we earned a then-record points tally of 99 to finish as Division Two champions. That he was a Spurs legend, winning the UEFA Cup, mattered little as he guided us back to the big time.
When Roberts left the Bridge a couple of a years later, it paved the way for young centre-half Jason Cundy to stake a regular claim for a first-team spot. Now, those of you who have seen Cundy on Chelsea TV will know he is blue through and through, having been brought up on the terraces at Stamford Bridge by his Chelsea-mad father. So it may come as a surprise for you to learn that he left the club to join Tottenham, although in his defence it was a decision that was made over his head.
Our Full Members Cup-winning squads of 1986 and 1990 contained players who performed with distinction for both clubs. In the former triumph, Colin Lee, who also helped us to promotion in 1983/84, scored twice in a thrilling 5-4 win over Manchester City in the final, with Micky Hazard, who had won his fair share of silverware with Spurs, on the bench. Then, in 1990 Clive Wilson was a sub as we beat Middlesbrough, and the left-back would later go on to represent Tottenham.
Two Spurs legends have managed Chelsea, albeit with varying degrees of success. Danny Blanchflower had won the Double during his time at N17, but by the time he took the reins at Stamford Bridge he was working at a club with limited funds and an uncertain future, and there was little to shout about. The same can't be said for Glenn Hoddle, though, whose Spurs legend status was firmly cast to one side as he led us to our first FA Cup final in 24 years in his first season as a our player-manager.
In more recent times, three of our Premier League winners from 2004/05 all ended up at White Hart Lane later in their career. Popular goalkeeper Carlo Cudicini was once the best keeper in the country while at Chelsea, and of course is now at the club as assistant to Maurizio Sarri, but he ended his decade-long stay in SW6 to try his luck at Spurs. Scott Parker eventually ended up there too, via a stint at West Ham United, which didn't seem to do his popularity any harm.
But William Gallas, who was a key part of our miserly defence which set a new English top-flight record for fewest goals conceded, made the unlikeliest transfer trail of Chelsea to Arsenal and then on to Tottenham. We still think his best moment was the stunning winner he scored for the Blues against Spurs in 2006.
As Greaves himself so famously put it, 'It's a funny old game.'
