On-loan Chelsea defender Kurt Zouma won't be able to play against us when we take on Everton this Sunday, but the Frenchman is part of an impressive group of players who have represented both clubs down the years.
Between the Toffees and Blues are no fewer than 39 major cups in the trophy cabinets, with the boys from west London holding the edge after a succession of silverware won during the Roman Abramovich era, while the Goodison Park club haven't lifted a trophy since the FA Cup in 1995.
On top of that, we also share plenty of history when it comes to players who have appeared for both the blue half of London and Merseyside.
Starting way back with Tommy Lawton, who had big shoes to fill at Everton – those of the great Dixie Dean, no less. He did so by twice finishing as Division One's top scorer and, following World War II, linked up with Chelsea for a prolific, albeit all-too-short spell, before a shock move to Third Division side Notts County for a record transfer fee.
Pat Nevin is well known to the current generation of Blues fans in his role as a columnist for both this website and the matchday programme, as well as featuring as a pundit for Chelsea TV.
However, for those fortunate enough to see him in his Eighties pomp, 'Wee Pat' was a jinking winger capable of moments of genius which had rarely been seen at Stamford Bridge before then. Indeed, the two-time Player of the Year was so popular in west London that when he returned with Everton and scored against the Blues, he received a standing ovation from both sets of supporters.
If Nevin was perhaps better suited to the modern era rather than the one he played in, the same certainly couldn't be said of Mark Hughes. The former Southampton manager was a battering ram of a centre-forward in his playing days, a role he played to good effect in a trophy-laden three-year spell at Chelsea.
Arguably his greatest moment for the club was his goal to book our spot in the 1998 Cup Winners' Cup final – a strike which he set-up by heading on a goal-kick to volley home himself. He was also briefly with the Toffees at the turn of the century, albeit with one eye on his role as manager of the Welsh national team.
We mentioned Everton's last major trophy before, and a former Blue player a key role in the club's victorious 1995 FA Cup final against Man United. Graham Stuart may have come up through the ranks at Chelsea and once scored a sensational solo goal against Sheffield Wednesday, but he enjoyed the best years of his career with the Toffees after joining them from Chelsea. He is still revered at Goodison Park for the goals against Wimbledon which ensured the club avoided relegation in May 1994.
Perhaps better known for being part of the “Damned United” under Brian Clough at Leeds – or, more impressively, for being able to hurdle Minis and throw a golf ball the length of a football pitch – Duncan McKenzie was blessed with dazzling skills but blighted by inconsistency throughout his career. He spent two years with the Toffees in the late-Seventies before a single-season spell with Chelsea in which the Blues finished bottom of the First Division standings.
Boyhood Blues fan Garry Stanley came up through the ranks at Chelsea to take his place in midfield for much of the Seventies. Known to team-mates and fans alike as Starsky thanks to his resemblance to one half of TV's crime-fighting duo Starsky and Hutch, he followed McKenzie out of the exit door at Stamford Bridge following the Blues' relegation and signed for Everton.
The appearance of Mickey Thomas on this list should come as no surprise – the journeyman winger did, after all, appear for no less than 12 clubs in his playing career. A brief stint with the Toffees was followed by a far more successful stay in west London as English football's loveable rogue played a pivotal role in our 1983/84 promotion campaign.
A peppy Glaswegian who swapped Rangers for Chelsea in 1992, John Spencer had to wait until Glenn Hoddle’s appointment as manager a year later before establishing himself. The striker formed an unconventional ‘little and little’ partnership with Mark Stein during the Blues’ run to the 1994 FA Cup final, while his goal against Austria Memphis in the 1994/95 Cup Winners’ Cup secured his cult hero status. That was one of 43 strikes for the Blues; his time with Everton was less successful, however.
Lastly, we come to Ben Howard Baker, who holds a unique place in the record books at Chelsea. The man who had spells at Everton either side of five years as a Blue has done something no other goalkeeper has achieved in the history of Chelsea Football Club: he scored a goal in a competitive fixture, albeit from the penalty spot. His all-round talents didn’t end there, for he also tried his hand at a number of different sports and represented Britain in the high jump at both the 1912 and 1920 Olympics!
