LONDON: Chelsea showed their Premier League title credentials, even without the injured Eden Hazard, as goals from Alvaro Morata, Ross Barkley (right), Willian and Ruben Loftus-Cheek sealed a comfortable 4-0 victory at struggling Burnley. Hazard, who was ruled out by a back problem sustained in a 2-2 draw with Manchester United last weekend, has been Chelsea’s main source of goals in an unbeaten start to the season under Maurizio Sarri. However, the visitors were stronger than their relegation-threatened hosts in every department and perhaps the only disappointment for Sarri was that they failed to underline their dominance with further goals. After a somber start with a minute’s silence to mark a helicopter crash that is feared to have taken the life of Leicester City owner Vichai Srivaddhanaprabha on Saturday, Chelsea were constantly in control and dispatched Burnley with ease. Meanwhile, Arsenal’s 11-match winning run came to a dramatic end as Luka Milivojevic’s late penalty rescued Crystal Palace in a contentious 2-2 draw. Unai Emery’s side failed to win a 12th successive match in all competitions as they fell short of the club’s record of 14 victories in a row. Arsenal fell behind to the first of two Milivojevic penalties just before half-time at Selhurst Park. Granit Xhaka equalized with a sublime free-kick before Pierre-Emerick Aubameyang poked in his ninth goal of the season in controversial circumstances. Arsenal striker Alexandre Lacazette flicked the ball to Aubameyang with his hand, but officials failed to spot the offense. Angered by that blow, Palace felt justice was done when Wilfried Zaha won a second penalty with seven minutes left and Milivojevic slotted home again. It was a frustrating afternoon for Emery, whose captain Mesut Ozil reacted angrily when substituted, the German throwing his gloves to the floor after stomping past the Arsenal manager.
