A little over four months ago, a dejected and disgruntled Manchester United team trudged off the field at FC Copenhagen's Parken Stadium having lost 4-3 to the Danish club in their UEFA Champions League group game. The home crowd was delighted, euphoric, but maybe not all that surprised. A fair few of them had, after all, seen this happen before.
Back in 2006, the club also known as FCK had qualified for the Champions League group stage for the first time in their history, and in just their second-ever home game they beat a Manchester United side that included Wayne Rooney and Cristiano Ronaldo.
