One of the most famed derbies in all of English football, Liverpool and Everton have played host to some of the greatest talents the sport has ever seen.
Unlike some of the fiery derbies debated as among the best in football, Liverpool and Everton's rivalry was traditionally solely a sporting one, with the game even gaining the moniker the "friendly derby" resulting from the number of families with split allegiances in the city.
However, despite their good-natured rivalry, relatively few players have "crossed the park" and represented both sides, with the phenomenon still just as rare in the Premier League era, despite the clubs no longer operating an official transfer embargo between one another.
So, who are the select few that have turned out for both Everton and Liverpool in the modern era? Let's take a look.
David Burrows
Liverpool 1988 - 1993: 34 Premier League appearances, 2 goals
Everton 1994 - 1995: 19 Premier League appearances, 0 goals
After emerging from boyhood club West Bromwich Albion, David Burrows was signed by Liverpool in October 1988 during Kenny Dalglish's time in charge of the Reds.
The England youth international would go on to be a consistent presence in the club's back line in the years that followed, and was a regular feature as the game transitioned into the Premier League era.
Burrows fell out of favour after Graeme Souness replaced Dalglish and moved to West Ham in 1993 as part of a swap deal that heralded Julien Dicks' brief spell on Merseyside.
After just a single season with the Hammers Burrows was on his way back up the M1, but his time at Goodison Park would prove to be similarly short lived, and he was on his way to Coventry City after just six months on the blue side of the Mersey.
Nick Barmby
Everton 1996 - 2000: 116 Premier League appearances, 18 goals
Liverpool 2000 - 2002: 32 Premier League appearances, 2 goals
Hull's greatest footballing son, Nick Barmby made an instant impact at Tottenham after emerging from the club's academy before joining Middlesbrough for a club-record fee in June 1995.
Just a single season in the North East later the left-sided midfielder was again on the move, this time joining Everton for £5.75million in what represented yet another record fee.
Barmby was one of the few players to endear themselves to the Everton faithful during a disappointing period for the club in which they failed to finish higher than 13th in four consecutive seasons.
That goodwill would quickly evaporate in the summer of 2000 when Barmby rejected a contract offer and subsequently informed then-Toffees boss Walter Smith that he wanted to join Liverpool.
Despite interest from Manchester United, a deal was eventually hashed out that saw the England international become the first player in more than 40 years to move directly from Everton to Liverpool.
In his first season at Anfield Barmby was part of the team that won the FA Cup, EFL Cup and UEFA Cup, but injuries curtailed his involvement the following year and he ultimately departed for Leeds.
Abel Xavier
Everton 1999 - 2000: 43 Premier League appearances, 0 goals
Liverpool 2002 - 2003: 14 Premier League appearances, 1 goal
Characterised by his distinctive bleached blonde hair, Portuguese full-back Abel Xavier played club football in eight different countries during a nomadic career that stretched from 1990 to 2008.
After impressing in the Eredivisie at PSV under Bobby Robson, Walter Smith brought the Portugal international to Goodison Park in September of 1999 to fill the void left by Olivier Dacourt's departure.
Despite injuries limiting his involvement Xavier was generally well-liked by Everton fans, with his departure serving as a example of the club's financial difficulties at the time.
With just months remaining on his contract, Everton reportedly offered Xavier a pay-as-you-play deal which was unsurprisingly rejected out of hand and Liverpool swooped in to sign him during the January window.
Xavier would go on to become the only player ever to have played for both teams in a Merseyside derby during the same season, but outside of that his time at Anfield was wholly unremarkable and he ultimately fell out of favour with Gerard Houllier.
Sander Westerveld
Liverpool 1999 - 2001: 75 Premier League appearances, 0 goals
Everton 2006: 2 Premier League appearances, 0 goals
Given the unenviable task of succeeding David James as Liverpool's No 1, Sander Westerveld arrived on Merseyside as the most expensive goalkeeper in British football after impressing in his native Netherlands.
Still relatively young for a shot-stopper at 25, the Dutchman enjoyed an impressive maiden campaign in the Premier League and picked up his first senior honours as the club completed their treble the following season.
Inconsistencies began to creep into Westerveld's game that season however, and unbeknownst to him Gerard Houllier had already set the wheels in motion to diversify his goalkeeping options going forward.
Within months Jerzy Dudek and Chris Kirkland had joined the club, with Westerveld abruptly finding himself third choice and he moved on to La Liga with Real Sociedad before later returning to the Premier League with Portsmouth.
At Fratton Park he again found himself on the outside looking in and he was permitted to join Everton on a temporary loan in February 2006.
With the club in the midst of a goalkeeping crisis with both Nigel Martyn and Richard Wright unavailable, Westerveld made two Premier League appearances for the Toffees before returning to the south coast.
Conor Coady
Liverpool 2010 - 2014: 1 Premier League appearance, 0 goals
Everton 2022 - 2023: 24 Premier League appearances, 1 goal
It's perhaps testament to Conor Coady's long and varied career in football that many forget that he is actually a product of the LFC Academy, having first signed with the club as a teenager.
A local boy and die-hard Liverpool fan, Coady captained the team's under-21 side and was rewarded for his performances in youth football with an appearance off the bench during the closing stages against Fulham in May 2013.
That brief cameo would ultimately prove to be Coady's only appearance for the Reds as he joined Sheffield United on loan the following year before sealing a permanent move to Huddersfield Town.
However, it was at Wolves that he enshrined his reputation as one of England's most promising young defenders and he went on to make 10 senior appearances for the Three Lions.
Despite being Wolves captain Coady joined Everton on a season-long loan in the summer of 2022, and he even put the ball in the net against his old club in his first Merseyside derby - only for it to be chalked off due to offside.
