Enzo Maresca admits Chelsea ‘need to improve many things off the ball’ after they were hammered 4-1 by Celtic in their pre-season friendly on Saturday night. Brendan Rodgers’ side ran out deserved winners at Notre Dame Stadium in Indiana as goals from Matt O’Reilly and Kyogo Furuhashi put the Scottish champions in front in the first half. #footballfanarena #ffa #Chelsea #celtic #enzomaresca #football #transferwindow
