"The United faithful began donning yellow and green scarves to protest against the Glazer family ownership. The Americans acquired a majority stake back in 2005 through the Red Football Ltd investment company, and five years later they had reportedly saddled the club with debts exceeding £700 million ($953m).
Red Devils supporters let their feelings be known by swapping in their red scarves for yellow and green, harking back to the days when they were known as Newton Heath. The club was originally founded under the name Newton Heath Lancashire and Yorkshire Railway Football Club in 1878, and eventually changed to Manchester United in 1902 before moving to Old Trafford eight years later."
