Chelsea on Friday confirmed that playmaker Eden Hazard is “major doubt” for Tuesday’s UEFA Champions League clash with Atletico Madrid at the Vicente Calderon stadium.According to assistant coach Steve Holland, “Hazard is not definitely out for Tuesday but he hasn’t trained with the squad yet which means he’s a major doubt,” he toldreporters. The former Lille midfielder limped out of the Blues’ quarterfinal second leg against Paris Saint-Germain two weeks ago, and has not played since.
