LONDON- AP Guus Hiddink has told Chelsea's underperforming players to look at themselves in the mirror and ask if they're up to the task of fixing the team. After Jose Mourinho was fired last week, the 69-year-old Hiddink was brought back for a second spell as manager until the end of the season. It followed Chelsea's alarming slump after collecting the English Premier League trophy in May. Chelsea has lost nine out of 17 games in the title defense to sit only three points above the relegation zone. Ahead of his first match in charge against Watford on Saturday, Hiddink said: "It's not easy to fix." Hiddink recounted telling the squad: "Look in the mirror for a long time and see what everyone from now on can contribute."
