Maurizio Sarri’s Chelsea look to capitalise on Arsenal’s stuttering Premier League form as they host Unai Emery’s side in a fierce London derby at Stamford Bridge on Saturday.
It’s fair to say that both clubs haven’t had it particularly easy this season, with both going through a period of transition with new managers.
In what could be one of the most interesting meetings between the two teams ever, it is difficult to predict a clear winner at this stage.
Ahead of the crunch clash in the race for the top four places, we have looked at three internationals that have dared to grace the shirts of both clubs.
Cesc Fabregas (Arsenal 2003-2011, Chelsea 2014-2019)
Midfield maestro Cesc Fabregas recently closed the curtains on his glittering career in England after he received a standing ovation in his final Chelsea appearance against Nottingham Forest.
A trip down memory lane will show him play for the red of Arsenal, which would be difficult to imagine after everything he has won for the Blues.
But he did and he made 212 domestic appearances for the Gunners from a period running across eight years.
Arsene Wenger sensed the talent that a young Fabregas had and snatched him from Barcelona at the age of 16 in 2003.
It wasn’t long before his talent came to prominence as he became the club’s youngest first-team player after the Spaniard made his debut in the League Cup.
He never looked back from that moment and was made the captain of the club in 2008 and remained in that role until his departure.
During his time with the Gunners, he won one FA Cup, the Community Shield and was also a runner-up in the 2005/06 Champions League final.
His lack of trophies was not mirrored by the performances of the Spaniard. Amid interest from his boyhood club Barcelona, he returned to the Catalan giants in 2011.
Fabregas appeared 151 times for Barcelona; he scored 42 goals and won a La Liga title, one Copa del Rey, two Spanish Super Cups and a FIFA Club World Cup.
His trophy-laden time in Spain was ended after Chelsea were keen to secure his signature. Jose Mourinho’s arrival sought a new revolution at Stamford Bridge and Fabregas was at the forefront of it.
He arrived in South West London in the summer of 2014 and made an immediate impact, winning the Premier League and the Capital One Cup in his first season.
The professionalism shone through during his latter seasons as appearances were few and far between. Despite this, he won the Premier League again in the 2016/17 season under manager Antonio Conte.
In May 2017, Fabregas lifted his final trophy with the Blues, beating Manchester United in the FA Cup final.
Fabregas parted company with the club to join Monaco earlier this month, to team up with his former Arsenal teammate and current Monaco boss, Thierry Henry.
The midfielder had an equally successful career on the international stage. He was a member of the ‘100 club’ for Spain as he made 110 appearances and scored 15 goals. In that time, he won the 2010 World Cup, as well as the 2008 and 2012 European Championships.
Petr Cech (Chelsea 2004-2015, Arsenal 2015-present)
Petr Cech announced this week that this season would be his last in professional football. This sent a wave of goodwill messages from his current and former teammates alike.
Undoubtedly the greatest goalkeeper in Chelsea’s history, the former Czech international signed for the Blues in the summer of 2004 after the arrival of Mourinho in his first spell.
Straight away, you could see why he was one of the most sought-after ‘keepers in the world.
Due to an injury to then first-choice ‘keeper Carlo Cudicini, Cech was promoted to the starting 11 immediately.
As soon as he was promoted, that was where he stayed for the vast majority of his Blues career.
In his first season, he helped his side win the league for the first time in 50 years, as well as the Carling Cup.
It was also a record-breaking season for Cech as he obtained a staggering 21 clean sheets in the Premier League and only conceded 15 league goals all season.
Next season was no different as the Pensioners claimed their second league title in as many years, whilst they only conceded 22 Premier League goals.
A moment of horror came in the 2006/07 campaign as he suffered a fractured skull in October following a challenge from Reading’s Stephen Hunt, which nearly cost Cech his life.
Thankfully, he returned to first-team action in January of the same season, equipped with a head guard which he would subsequently wear for the rest of his playing career.
Despite his woes, the shot-stopper still won the FA Cup against Manchester United in the final at the newly built Wembley Stadium in the same season.
Club heartbreak followed in the 2007/08 season as they were defeated in the Champions League final at the hands of United in Moscow.
In what was a season of inconsistency in the 2008/09 term, Chelsea sacked manager Luis Felipe Scolari and brought in Guus Hiddink, in which they won the FA Cup again and finished third in the league.
The arrival of Italian manager Carlo Ancelotti in the 2009/10 season brought much-needed excitement to the club as the free-scoring Blues went on to win the Premier League for the third time, as well as retaining the FA Cup.
It looked to be a season full of disasters during the 2011/12 campaign, as the club sacked manager Andre Villas-Boas after poor results in the league and almost being booted out of the Champions League in the knockout stages.
However, Roberto Di Matteo took interim charge and brought the side back together, as they not only won the FA Cup once more but the Champions League for the first time ever. In what was the greatest night in the history of the club, Cech played a vital part throughout the campaign as Chelsea got their hands on the one trophy they had been craving.
A Europa League triumph in the following season would be his last trophy as the first choice goalkeeper. After several loan spells away from the club, Thibaut Courtois arrived and was the preferred choice in the title-winning 2014/15 season. Cech did, however, start in goal as his side came out victorious in the League Cup final against Tottenham Hotspur.
Due to his lack of playing time and reluctance to move away from London, he signed for Arsenal in the summer of 2015 after nine years and almost 500 appearances for the Blues.
He won the FA Cup in the following season, which was the fifth time he lifted the famous trophy.
After his retirement announcement earlier this week, there is no doubting Cech’s services as one the most important figures that Chelsea have ever had.
Cech was also ever-present for the Czech Republic national team, playing in 124 matches over a 14-year period.
Nicolas Anelka (Arsenal 1997-1999, Chelsea 2008-2012)
It’s quite difficult to find a starting point with Nicolas Anelka as he played for a staggering 13 clubs throughout his impressive career.
The Frenchman started footballing life at Paris Saint-Germain but moved to Arsenal at the age of 17.
He broke into the first-team in the following season and helped the Gunners to win the Premier League and FA Cup double in the 1997/98 season.
Anelka was named as the PFA Young Player of the Year after scoring 17 league goals the season afterwards but he failed to win a piece of club silverware.
It wasn’t all good for the promising forward as he announced his desire to leave the club. In 1999, he joined Spanish giants Real Madrid.
Following spells at Liverpool, Manchester City, Fenerbahce and Bolton Wanderers, he signed for Chelsea in January of 2008 for £15 million.
His influence was noted as he won the Golden Boot in the 2008/09 after scoring 19 league goals.
The French forward was vital in Chelsea’s double-winning 2010/11 campaign. He scored 11 league goals as well as two in the final game of the season in an 8-0 thrashing against Wigan Athletic.
Villas-Boas’ arrival as the new manager pretty much signalled the end of Anelka’s Chelsea career, as he was keen to favour younger talent over his ageing squad.
Anelka signed for Chinese club Shanghai Shenhua in January of 2012, but it wasn’t long before he was back in the Premier League.
After a loan spell with Italian giants Juventus, he signed for West Bromwich Albion for a season before leaving for Mumbai City FC.
Mumbai would prove to be his final destination in professional football as he announced his retirement at the end of the 2014/15 season.
For France’s national side, Anelka played 69 times and scored 14 goals but following a fallout with French manager Raymond Domenech in the 2010 World Cup, he was sent home and subsequently announced his retirement from international football.
