LONDON: Chelsea booked their place in the last 16 of the Champions League as first-half goals from Tammy Abraham and Cesar Azpilicueta sealed a 2-1 win over a much-changed Lille at Stamford Bridge. Victory for Valencia over Ajax in the other game in Group H means Frank Lampard’s men go through behind the Spaniards with last season’s semi-finalists relegated to the Europa League. Chelsea knew victory would take them into the knockout stages no matter what the outcome was in Amsterdam and did their job early on against a Lille side with just one point to show for their return to the Champions League for the first time in seven years. Simple finishes from Abraham and Azpilicueta were just reward for a dominant first-half display, but Chelsea were forced to hold on in the final stages after Loic Remy halved Lille’s deficit against his old club 12 minutes from time. The visitors were already sure to finish bottom of the group and coach Christophe Galtier showed his priority is trying to secure a return to the Champions League next season by finishing in the top three of Ligue 1 as he made seven changes to the side that beat Brest on Friday. Chelsea had won just one of their previous five games after a great start to life under Lampard and the Blues boss responded by adding a little more experience to what has been a very young side so far this season.
