Mason Mount took a swipe at his former club as Manchester United secured a narrow 1-0 victory over Chelsea FC at Stamford Bridge.
Mount, introduced late in the game, drew attention when he gestured toward the home crowd in a moment that appeared to mock the frustrated supporters.
Chelsea, managed by Liam Rosenior, endured their third straight Premier League defeat on home soil, a result that further dents their hopes of breaking into the top five.
Despite hitting the woodwork three times, the hosts failed to convert their chances, struggling to find the cutting edge needed to salvage a result.
United, meanwhile, capitalised on Chelsea’s profligacy to claim all three points, leaving the home fans increasingly agitated as the final whistle approached.
