Ranking Chelsea's 5 best transfer windows

#2 "I choose the Champions League winners" (2012-2013)

Belgian Eden Hazard moved to Chelsea from Lille for £32 million

It would be hard to find someone who would disagree with the notion that Eden Hazard is one of the most talented players ever to grace the pitch at Stamford Bridge.

After a whirlwind season in which Chelsea finished 6th in the league while winning the FA cup and their first ever Champions League, Hazard decided to sign for Chelsea for a fee of £32 million while making his European ambitions clear.

His dream of winning the Champions League hasn't been fulfilled yet, but 6 seasons, 275 appearances and 81 goals later, he has cemented his place as a Chelsea legend. In hindsight, the fee that the club paid for him looks to be an absolute bargain as he carried the side and still does, through thick and thin, with his ethereal vision and mazy dribbling.

Another signing which definitely went under the radar when it happened was the £7 million purchase of Caesar Azpilicueta from Marseille. He was initially bought as a backup to Ivanovic for the right-back spot.

But no one ever imagined that he would go on to make the left-back spot his own over the years to come. His ability to play anywhere in the back line makes him a prized asset for the team.

Sharing the dressing room with stalwarts like John Terry, Frank Lampard and Didier Drogba has also improved his leadership qualities. Qualities which he uses today to organise and lead the team from the back.

Both Hazard and Azpilicueta have been indispensable for the team and will continue to be so for many more years to come, making this particular transfer window a rather significant one.
