Last season he was lighting up the Premier League and the envy of every club in world football; now, Chelsea must seriously consider letting their most talented player leave the club.
Following a series of recent injuries that have seen Eden Hazard dip in and out of the team, rumours of discontent continue to grow. The midfielder is clearly unhappy and it's no wonder given his failure to score this season.
Any suggestion prior to the campaign that the Belgian wouldn't have scored after 21 league games would have been ridiculed, yet here we are, mid-way through the January transfer window, and Hazard's lack of goalscoring threat epitomises the Blues' struggles throughout 2015/16.

The Belgium international may have watched his team improve since Guus Hiddink's return to Stamford Bridge as interim manager, but rumours implicating his desire to leave continue to emerge.
Real Madrid and Paris Saint-Germain would both appeal to the 25-year-old and are reportedly interested in acquiring his services, whilst Manchester City have also sounded their intentions to launch a bid.
It would require a huge fee for the transfer to go ahead and Chelsea might be hesitant to let their prized asset leave at the first sign of decline, yet Hazard departing Stamford Bridge could be best for the west Londoners.
Perhaps the biggest problem for Chelsea is what to do if he does leave; who could they bring in as a replacement?
Gareth Bale has long been touted with a return to the Premier League, but following his hat-trick heroics against Deportivo over the weekend, it's likely the Welshman will firmly feature in new manager Zinedine Zidane's plans at Real Madrid.
A player of Bale's quality is exactly what Chelsea must pursue in replacement of Hazard - but would the Wales international fancy the move? Unlikely given his loyalty to previous employers Tottenham Hotspur and perhaps even more so given the sheer amount of interest in the winger.
The problem for Chelsea, therefore, is not simply losing Hazard, but who could suitably replace him should the day come that he is sold. Quite the dilemma, it seems.
