Chelsea are one of the biggest clubs in world football.

While the Stamford Bridge side might find themselves in uncertain territory with their owner, Roman Abramovich, sanctioned by the UK and EU, there's no denying their stability on the pitch.

The Chelsea men's first-team have been superb under Thomas Tuchel's management, winning the Champions League, UEFA Super Cup and FIFA Club World Cup alongside reaching two domestic finals.

The strength in Chelsea's squad

Sure, the Premier League title might have passed them by this season, but what the Blues have achieved in the last 12 months when they share a division with Manchester City and Liverpool is simply superb.

Obviously, a lot of the credit goes towards Tuchel for the stellar impact that he's made since replacing Frank Lampard, but there's also a lot to be said for the squad itself.

Chelsea's dressing room currently strikes a fantastic balance between young, exciting players like Kai Havertz and Reece James and the established, senior stars such as Cesar Azpilicueta and N'Golo Kante.

And with the alarming potential that some of these players could slip through Chelsea's fingers amidst the current regulations, now felt like the perfect time to take stock of the club's playing staff.

So, we've decided to separate the diehard Chelsea fans from the plastic supporters by drawing up a quiz that asks one question about every single member of the squad.

Well, to be specific, anyone still at the club who was named in their 2021/22 Premier League squad or has made an appearance for the Blues in England's top-flight this season.
