Chelsea boss Maurizio Sarri reportedly singled out Eden Hazard for criticism after the 4-0 defeat to Bournemouth on Wednesday night.
The Blues conceded four second-half goals at the Vitality Stadium, and the capitulation led to Sarri keeping his players in the changing room for an hour after the match.
According to The Telegraph, Sarri took aim at Hazard by accusing the club's star man of failing to follow his pre-match instructions.
The report also claims that the Italian feels that his team are not playing to his tactics, but the criticism of Hazard comes at a time when Chelsea are doing everything they can to keep the Belgium international at Stamford Bridge.
Hazard - who now has less than 18 months left on his contract - has been heavily linked with a summer switch to Real Madrid, and Sarri has recently said that the playmaker is 'free to leave if he wants'.
