Chelsea have confirmed their squad numbers ahead of the 2020/21 season.
With five new first-team signings and a couple of departures, changes have been made.
Most notably, Christian Pulisic has taken the famous No.10 shirt following Willian's move to Arsenal.
New boy Hakim Ziyech takes his old shirt - number 22 - while the two other big-name signings Timo Werner and Kai Havertz will wear 11 and 29 respectively.
With the number 10 on his back, Pulisic might well feel added pressure to perform at Stamford Bridge.
After all, the number is one of the most famous in football and Chelsea have had their fair share of legends wear the shirt.
So with that in mind, here at GIVEMESPORT, we've decided to rank the club's seven number 10s since 2000 from worst to best.
7. Yossi Benayoun (2010/11)
Benayoun is still one of those signings that makes Chelsea fans think 'but why?'
He arrived from Liverpool in 2010, took the shirt, played 10 times in all competitions and scored just once.
The following season, he lost the shirt to Juan Mata. But more on him later.
6. Slavisa Jokanovic (2000/01 - 2001/02)
Before Jokanovic made a name for himself as a manager, coaching the likes of Watford and Fulham, he was actually a Chelsea player.
Sadly, he had a rather forgettable spell at Stamford Bridge. The Yugoslavia international played 53 times in two seasons, but at the age of 34, was at the end of his career.
He retired shortly after being released by the Blues in 2002.
5. Christian Pulisic (2020/21)
Pulisic has only had one season to prove himself at Stamford Bridge, but it's already clear he'll be better than Jokanovic and Benayoun.
In fact, he could soon overtake those ahead of him on the list. In his first season at Chelsea, the American scored 11 goals and provided 10 assists in 34 games.
The forward is going to be a star for many seasons to come and is certainly deserving of the No.10 shirt.
4. Juan Mata (2011/12 - 2013/14)
One of Chelsea's best signings of the last decade, Mata was a true number 10.
He spent just three seasons in London but quickly became a fan favourite, scoring 33 goals and providing 58 assists in 135 matches.
The Spaniard was also key in securing FA Cup, Europa League and Champions League glory during his time at Chelsea.
3. Willian (2019/20)
Willian only wore the shirt for one season, but his contribution to Chelsea prior to that can't be overlooked.
Often under-rated by many fans, it's easy to forget that the Brazilian spent seven brilliant seasons at Stamford Bridge, contributing 63 goals and 62 assists in 339 games.
He also won two Premier League titles, the FA Cup, the League Cup and the Europa League. Not bad at all.
2. Joe Cole (2003/04 - 2009/10)
Now, Cole may not have been the most dazzling of number 10s, but he's remembered by fans as one of Chelsea's best players from their glory era.
Like Willian, he spend seven seasons in west London and was a key player throughout, scoring 40 goals and assisting 42 times in 281 games.
It's his trophy haul that puts him high on this list. Cole won three Premier League titles, two FA Cups, the League Cup and the Community Shield with Chelsea.
1. Eden Hazard (2013/14 - 2018/19)
Was there ever any doubt that Hazard would top this list. When you compare him to Chelsea's other No.10s, no one comes close.
Regarded as one of the best players in Europe throughout his time at Stamford Bridge, the Belgian often carried the club on his back and was the match-winner on numerous occasions.
110 goals and 92 assists in seven seasons is impressive alone, but just remember that Hazard almost single-handedly dragged the Blues to Europa League glory in his final campaign.
On top of winning the Europa League twice, he left the club as a two-time Premier League winner, while also getting his hands on the FA Cup and League Cup. Legend.
Well, it seems Pulisic has a lot to live up to. But it wouldn't be surprising to see him surpass the legacies of Cole, Mata and Willian.
To be named Chelsea's greatest ever No.10 though, he'd have to de-throne Hazard and that will be quite the challenge.
