Since arriving at Stamford Bridge in 2012, it's safe to say that Eden Hazard has established himself as one of the brightest and most consistent talents in the Premier League.
The sum of £31.5m the Blues forked out to Lille for his services seems an outright bargain given the current financial climate in football.
Throughout his time in the English top flight, Hazard has helped Chelsea to two league titles, an FA Cup and a League Cup.
This season, however, under a new coach and a drastically different tactical outlook, the 28-year-old - along with the rest of the team - has struggled to keep up with some of the league's frontrunners.
Maurizio Sarri's men currently sit sixth in the Premier League table, three points off the top four.

For years, Hazard has been linked with a move to Spanish giants Real Madrid - a deal that would undoubtedly require Los Blancos to fork out a pretty penny.
However, according to AS, Madrid's valuation of the Belgian forward could come as a surprise to some.
The Spanish paper claim that the club estimate a move for Hazard would cost between £85m and £100m.
To put that into context, Madrid value the 28-year-old only at £15m more than what Chelsea paid for Kepa Arrizabalaga last summer.
With Zinedine Zidane returning to manage Los Blancos, club president Florentino Perez will hope the team can soon turn around their questionable form - even if it means spending big in the summer.
Reports previously suggested Madrid were eyeing Manchester City winger Raheem Sterling as part of a £300m summer squad rebuild. It has also been suggested that one of Zidane's terms for re-joining the side was having the financial backing to improve his squad.
Chelsea's transfer ban may disrupt Real's plans to swoop in for their Belgian star slightly. However, the prospect of working under Zidane and the rest of the world-class talent at Madrid may pry Hazard away from the Blues' grasps, especially if the two clubs settle on the right price.
