It's been a bizarre 10 years for Chelsea.

One minute they're absolutely romping their way to the Premier League title, the next they're limping to a 10th place finish or being eliminated from the FA Cup by Bradford City. It's certainly been a ride.

However, there have definitely been more ups than downs, no less than in 2012 when Chelsea won their maiden Champions League crown with that unforgettable night in Munich.

And we can reliably inform you that picking Chelsea's best starting XI from between 2010 and 2020 is easier said than done. Nevertheless, we've given it our best shot.

So, factoring in all those memorable highs as well as the damning lows, here is GIVEMESPORT's selection for the greatest Chelsea side this decade has ever seen.

GK - Petr Cech

A tougher call then you'd imagine. Thibaut Courtois has a pretty good argument for selection with two Premier League titles, an FA Cup, League Cup and Golden Glove in just four seasons.

But for that night in Munich alone, it simply has to be Cech. The club legend still produced some of his greatest moments and saves post-2010, boasting a trophy collection - including two Golden Gloves - that his successor could never match.

RB - Branislav Ivanovic

One of the most underrated players in Premier League history. The Serbian was an absolute juggernaut for the Blues and even had an eye for goal, scoring 31 times since the turn of the decade.

CB - John Terry (C)

We'll let Terry's trophy cabinet since 2010 speak for itself: three Premier League titles, two FA Cup wins, the Champions League, Europa League, League Cup, Community Shield and a PFA Team of the Year appearance.

Terry is the greatest captain in Chelsea's history and even in the twilight years of his career, the legendary Englishman was near enough unrivalled.

CB - Gary Cahill

What an absolute steal at £7 million. Cahill went on to make almost 300 appearances for Chelsea, finishing his spell at Stamford Bridge as club captain and even scoring 25 goals for good measure.

LB - Ashley Cole

It seems cruel that Cesar Azpilicueta doesn't feature somewhere in this back four, yet we simply can't omit Cole when he finished the first season of the decade as the world's best left-back.

His regular appearances quickly dried up when Jose Mourinho returned, but he was absolutely pivotal during the 2012 Champions League run and neutralised countless world-class wingers.

CDM - N'Golo Kante

Chelsea's best signing of the decade? Kante is certainly in with a shout, rounding off his first season in west London with a second consecutive Premier League title and the PFA Player of the Year award.

The hype might have plateaued in recent seasons, but the World Cup winner also has an FA Cup crown and Europa League title to show for his incomparable efforts.

CM - Frank Lampard

Duh. Lampard entered the decade with an insane 27-goal season, before finding the net 17 times during his penultimate campaign and becoming Chelsea's all-time top scorer before his 2014 exit.

CM - Cesc Fabregas

You get the feeling that Chelsea snapped up Fabregas just a few seasons too late, but the Spaniard was playing football from another planet during the 2014-15 campaign, collecting an eye-watering 18 assists.

And even as his star faded under Antonio Conte and Maurizio Sarri, the former Arsenal man was never far from a moment of magic than none of his teammates could ever produce.

CAM - Eden Hazard

One of the greatest players in Premier League history. The anomalously terrible 2015-16 season aside, Hazard was always lethal in front of goal and waved goodbye to Stamford Bridge with 110 strikes to his name.

The likes of Pedro, Florent Malouda and Willian also deserve honourable mentions, despite comfortably missing out behind a stellar midfield.

ST - Didier Drogba

Imagine starting the 2010s with a Premier League title and the Golden Boot, closing out your Chelsea spell with a Champions League win and then coming back just to win the league again. That's Drogba and that's case closed.

ST - Diego Costa

What on earth were Chelsea thinking when they sold Costa? Conte should never have dropped the axe on a Spanish striker who was head and shoulders above any of the post-Drogba forwards that Chelsea have bought.

Twenty goals in his first season, 16 in his second and then a final campaign of 22 strikes means that Costa unquestionably deserves his place in the team. What an insane front two this would be.

In summary: Chelsea have had some fantastic players over the last decade.

Considering what the club achieved with these players jumbled up and interspersed, Chelsea would have won untold treasures if that XI all played together at their peak, never mind for 10 years.
