Chelsea are concerned about the condition of star attacker Eden Hazard after the game against Manchester United.

The Blues emerged from the game with a 2-2 draw, but they are sweating over Hazard's fitness.

Per The Sun, Hazard complained about back problems after the game.

It may have something to do with Manchester United's strategy to strategically foul Hazard with different players throughout the game.

Chelsea boss Maurizio Sarri will be hoping Hazard is back in time for the weekend's Premier League games, but he is likely to miss the midweek Europa League clash against Bate Borisov.
