Celtic delivered a commanding 4-1 defeat to Chelsea in a pre-season friendly at Notre Dame Stadium, Indiana, marking another setback for the Premier League side under new manager Enzo Maresca. The Scottish champions took an early lead through Matt O'Riley and doubled their advantage with a goal from Kyogo Furuhashi, showcasing their clinical finishing and strong teamwork. Chelsea struggled defensively, allowing Celtic to capitalize on mistakes, leading to further goals from Luis Palma and Mikey Johnston. Although Christopher Nkunku netted a late penalty for Chelsea, it was a mere consolation in a match where they displayed little cohesion. The defeat follows a disappointing 2-2 draw against League One's Wrexham earlier in the week, leaving Chelsea without a win in their US tour. Fans expressed frustration over the team's performances, fearing for their prospects in the upcoming Premier League season.
