Eden Hazard has told close friends that Jose Mourinho is the worst coach he's ever worked with, according to French source RMC.
The Belgium international criticised his team's tactics following the 3-1 defeat to Atletico Madrid on Wednesday night, saying the team is not set up to play football.
He told reporters: "Often, I'm asked to do it all by myself and it's not easy.
"Chelsea aren't set up to play football. Chelsea are set up to counter-attack."
It is now being reported that Hazard is fed up with the defensive tactics of Mourinho and has gone as far as telling friends that the Special One is the worst manager he has worked under.
Sources close to the player told RMC that despite maintaining a healthy relationship with Mourinho, the fact remains that Hazard does not correlate with his tactics.
It even says that Hazard, who has been linked with a big-money move to Paris Saint-Germain, is considering his future at Stamford Bridge because Mourinho is likely to be there for the long-term.
The 23-year-old has been a standout performer for Chelsea this season, earning the PFA Young Player of the Year award in the process.
The Express reported that PSG were willing to spend as much as £50m to make sure Hazard is playing at Parc des Princes next season.
Mourinho himself claimed only an offer of £300m - including Chelsea star Oscar as well - would tempt him to sell Hazard.
However, if the Belgian wants to move, there is little Mourinho could do to stop him. Having an unhappy player on the books is not something any manager in the mould of Mourinho would accept.
