Manchester United's top six heaviest defeats in UEFA Champions League history ft. Como

The Red Devils have suffered some embarrassing defeats in the UCL. Despite their troubles over the last decade, Manchester United remain one of the biggest clubs to take part in the UEFA Champions League.
The Red Devils have won the English top flight 20 times, but their dominance also extends to Europe's premier continental competition. United have won the UCL title an impressive three times.
Their first continental title came in 1968, beating Benfica 4-1 in the final. A 2-1 win against Bayern Munich in 1999 clinched their second continental title.
Their last UCL title came in 2008, when they beat Chelsea on penalties. However, such days of glory feel like distant history at the moment.
United have gone through a tough period since Sir Alex Ferguson 's retirement in 2013. This season, too, has been a challenge on both domestic and continental fronts.
The Red Devils remain winless in the UCL this season under head coach Michael Carrick. They suffered an embarrassing 4-1 defeat at the hands of Serie A side Como.
This marked one of the club's heaviest defeats in Champions League history. However, it is not the heaviest defeat they have suffered in the UCL.
Let's look at the six heaviest defeats suffered by United in Champions League history.
