Claudio Ranieri and Andre Schurrle return to Stamford Bridge with Fulham on Sunday, but they are far from the only former Blues to have featured for both of west London's top two clubs.
The Tinkerman got off to a winning start as Whites gaffer last weekend, having replaced Slavisa Jokanovic at the helm. In a strange twist of fate, the Serbian manager was actually Ranieri's first signing when he took the reins at Chelsea in September 2000, joining us from Deportivo La Coruna soon after.
He is one of a long list to have been associated with both of the SW6 sides, which also includes a current member of the Fulham squad as Schurrle, who netted in Ranieri's debut fixture in the dugout, was a Premier League winner during his time at Stamford Bridge.
In fact, the German, who also lifted the World Cup in 2014, was the hero the last time we met our neighbours. He scored a fantastic hat-trick in the space of 17 second-half minutes to give us a 3-1 victory over Fulham in March 2014, a result which moved them a step closer to relegation and a four-year absence from the top flight. When they eventually came back up via the play-offs last season, two on-loan Blues players, Tomas Kalas and Lucas Piazon, played their part in that successful campaign.
Another man to score a hat-trick in this fixture was Gordon Davies, who also achieved it at Cottage Cottage in 1983, only this time he was wearing the white shirt of Fulham. The moustachioed centre-forward still ended up on the losing side, though, as Kerry Dixon and Pat Nevin combined to great effect to lead us to a 5-3 victory, but Fulham's all-time leading scorer clearly left a lasting impression on Chelsea as he later went on to enjoy a short stint at the club.
One of Davies' team-mates at Chelsea was Doug Rougvie, who older Blues fans will remember for his whole-hearted displays in one of the biggest back fours in the club's history, alongside Colin Pates, Joe McLaughlin and Colin Lee. Or, more likely, they will recall the last-minute penalty he gave away against Sheffield Wednesday in an epic League Cup tie which had seen us come from 0-3 down to lead 4-3 and also his comical own goal in our famous 5-4 win over Man City in the Full Members Cup final. Less memorable was his spell at Fulham a few years later.
Rougvie's manager at Craven Cottage was Ray Lewington, who enjoyed the best years of his playing career alongside the River Thames after starting his career at Chelsea and winning promotion as part of Eddie McCreadie's popular young side in the Seventies. Ray Lew took his first steps in management at Fulham and later spent a long time working as a coach there, most notably working alongside Roy Hodgson when our neighbours made it all the way to the Europa League final in 2010.
The Whites were narrowly beaten in that game, but one of the stars of that run had been Damien Duff, who was previously a star at Stamford Bridge after joining us in the first summer of the Roman Abramovich era. The Irish winger was a huge hit with the fans and, in tandem with Arjen Robben, he was one of the key men as we lifted the Premier League title in back-to-back seasons, as well as winning the League Cup in 2005.
Another Chelsea title winner proved to be a big hit at both the Bridge and the Cottage. Roy Bentley was the captain and talisman for Ted Drake's side in 1954/55, finishing as our leading scorer as we became champions for the first time in our history. He was a centre-forward in his time as a Blue, but the move across SW6 also saw a change in position, as he excelled as a centre-back to help Fulham reach an FA Cup semi-final in 1958.
Bentley passed away earlier this year at the age of 93, shortly after we also said goodbye to another Blues legend who had a spell at Fulham. Ray Wilkins was the young skipper of McCreadie's aforementioned side in the late-Seventies which was so adored by the supporters and Butch was the best of the bunch, a playmaker who also chipped in with some sensational goals. One of his early managerial gigs was with Fulham, and he later became assistant manager there, but the best days of his coaching career were at the Bridge as he first won the FA Cup in 2000 and later returned to help inspire our 2010 Double triumph.
Bobby Campbell is another to have worked on the coaching staff at both SW6 sides, starting his managerial career with Fulham and going on to lead Chelsea to promotion in the 1988/89 season, while Mark Hughes was an FA Cup winner, among others, during his time with the Blues and also a former Whites boss.
John Dempsey was part of Chelsea's FA Cup-winning side in 1970 and then a year later he lit up the Cup Winners' Cup final against Real Madrid with a scorching volley that any centre-half would be proud of. Not only did he join us from Fulham, but he'd grown up watching both sides as his dad would take him to Craven Cottage one week and Stamford Bridge the next!
The list just goes on and on. Three full-backs, Wayne Bridge, Paul Parker and Jon Harley, had their moments for both clubs; Teddy Maybank represented both and even found time to make an appearance on Blind Date; Clive Walker scored the goal which kept Chelsea in Division Two in 1983 and later made over 100 appearances for Fulham; Bjarne Goldbaek netted one of the best Blues goals against Tottenham before moving across west London.
It seems an Australian soap had it spot on when it comes to good neighbours...
