Chelsea can now look back at the last decade as a memorable one that saw them continue to compete at the elite level.

The Blues won two Premier League titles, two Europa Leagues, two FA Cups and a League Cup during the decade, but perhaps most importantly was the 2012 Champions League win in Munich.

There have been a number of incredible players that have played their role in the success, but who has been the biggest transfer bargain of the decade?

Cesar Azpilicueta moved to Stamford Bridge for £7million (Guardian) back in 2012 from Marseille and he’s the number one pick as the biggest bargain.

It’s no exaggeration to state he was at one point one of the best defenders in the Premier League for a number of years and played a vital role in two title wins.

His incredible versatility to play either full-back role or at centre-back highlights his class, as well as becoming a big leader in the dressing room.

But above all the Spanish defender has hardly missed a game due to his professionalism and commitment, which is why he’s become a club legend in the process and his £7million transfer was an absolute steal.

Honourable mentions:

N’Golo Kante: It seemed remarkable that Chelsea won the race for the French midfielder after his heroics in Leicester City’s 2015/16 Premier League title triumph. He’s proven to be a £30million (BBC) bargain for the Blues, as he has been a world-class player for a number of years and won three pieces of silverware at Stamford Bridge.

Gary Cahill: Chelsea snapped up the defender for just £7million (BBC) from Bolton Wanderers in 2012 and toking back the was a masterstroke. He took on the mammoth task of following in the footsteps of John Terry and the no-nonsense defender won two league titles at the club.

Eden Hazard: There was much excitement around West London when Chelsea signed Hazard for £32million (BBC) in 2012 and the attacker lived up to the hype. The Belgian playmaker left a club legend last summer when he exited for Real Madrid and is one of the most exciting individuals to ever wear the Blues shirt.
