There was a great moment at the Stadium of Light on Sunday afternoon as Jose Mourinho turned around to ask Michael Carrick for help in deciphering what the away fans were singing about.
With the game wrapped up inside the first minute of the second fans, it was an opportunity for the travelling United supporters to to go through their back-catalogue of chants unopposed as the home fans came to terms with the fact that it wasn't their day.
Wes Brown and John O'Shea both got some love as former Sunderland men, but it was Diego Forlan's name that Mourinho could not quite work out, and when informed by Carrick, seemingly couldn't understand why.
In his regular article for The National, Forlan admitted that he did not see the footage live even though he was watching most of the game as he was moving house at the time, but once he learned of what happened it warmed his heart.
Soon after the match ended, I received messages which showed television footage of Jose Mourinho turning to Michael Carrick to ask who Diego was. United fans were singing about me in the away end, something which I cannot believe still happens.
I loved my time at United and had a good relationship with supporters, but I am sure there are many others who say exactly the same, some of them who had more successful careers at the club than I had. And they do not get their names sung.
It is all very flattering, but I love that catchy little song: "Diego, wooah, Diego, wooah, he came from Uruguay, he made the Scousers cry".
People still come up to me wherever I am in the world and remind me of two goals scored in a Premier League match 15 years ago more often than they do about my goals which saw me as the top scorer in the 2010 World Cup.
Forlan then gave recent examples from fans in Mauritius and India to hammer home just how far and wide those goals reached, before revealing that even Liverpool fans remind him of those goals to this day.
Even Liverpool fans approach me and say "I won’t forget who you are". I wonder whether it is because my goals for Atletico Madrid knocked them out of Europe, but it is probably those two for United – they stick in the mind because it was the first time in 10 years that United had won at Anfield.
Gary Neville knew the significance. He said immediately after that game: "You don’t know what you have done, Diego. You and they [the fans] will always remember it."
Knowing full well what he's doing bringing up his Atletico goals there as well, the cheeky so and so.
His time at Man Utd was not a roaring success as he bagged 10 goals in sixty-odd games, but a double at Anfield when the club had not won there for 10 years was enough to cement his cult status.
He would, of course, go on to prove his class over the rest of his stellar career, but there are many Man Utd players who have done far more of the club that don't get a song that stands the test of time.
