WATCH: Mourinho Asks Michael Carrick Why Man Utd Fans Sing About Diego Forlan
Manchester United got back to winning ways after a couple of drab draws with a win over bottom club Sunderland at the Stadium of Light.
Zlatan Ibrahimovic scored the opener half-an-hour into the game when he collected the ball on the edge of the box, displayed unrivalled strength to hold off Billy Jones and rolled the ball into the bottom corner for his 27th goal in all competitions this season.
His compatriot Sebastian Larsson was sent off in the first half after referee Craig Pawson deemed his challenge on Ander Herrera to be over the top and dangerous.
That killed any hopes of Sunderland giving a good account of themselves and from then on it was a routine win and display for United.
Henrikh Mkhitaryan struck a minute after the restart, before Ibrahimovic played substitute Marcus Rashford through in the last minute to make it 3-0.
With United comfortable and untroubled throughout, the away fans were in fine voice and decided to sign about some of their United heroes.
Cantona and Ronaldo got a mention but there was also a chant for Uruguayan forward Diego Forlan, who spent two years at United between 2002 and 2004 before turning out for the likes of Villarreal, Atletico Madrid and Inter Milan.
United fans still remember his double that sunk Liverpool in December 2002 at Anfield and still sing his names to this day.
However, manager Jose Mourinho was left slightly bewildered as to why his club's supporters were singing about Forlan.
But with the game petering out in the second-half, the Special One could be seen turning to Michael Carrick and enquiring exactly who 'Diego' is:

When Carrick responds with 'Forlan', Jose understandably asks why, and on the face of it, the Uruguayan striker didn't have the greatest of spells at Old Trafford.
However, if you score the winner against Liverpool, you'll be fondly remembered by United fans, as is the case with Forlan.
Every day a school day, Jose.
