Sarri made five changes from Saturday’s 4-1 win against Cardiff with Eden Hazard, who Sarri says has complained of tiredness twice in the last month, being rested along with David Luiz and Mateo Kovacic.
Chelsea manager Maurizio Sarri has won all of his group stage games in the Europa League (seven out of seven), keeping five clean sheets in this run.
Chelsea missed a number of chances to make the scoreline more emphatic and Morata was the biggest culprit. The Spain striker headed wide from a Pedro cross before dragging a left-footed shot wide from Antonio Rudiger’s throughball.
And after being unable to keep a sidefoot volley down, Morata blazed over left-footed from the left side of the box.
Willian’s early goal from Ross Barkley’s lay-off was enough for a much-changed Blues side to maintain their winning start to the season in Greece, despite playing in front of a raucous sold-out crowd in Thessaloniki.
Chelsea manager Maurizio Sarri said the Europa League could “be a problem” later in the season after his side began their campaign with a 1-0 win at PAOK Salonika.
