With the match just minutes old, Forest fans launched into a chorus of: "Champions of Europe, you'll never sing that," in reference to their European Cup wins in 1978/79 and 1979/80.
That choice of song was always going to annoy Arsenal fans, with the 'Gunners' having never claimed the title of European champions.
However, rather than become angry, Arsenal's fans went one better, replying in kind with a round of: "Champions of Europe? You weren’t even born".
The exchange brought a smile to the faces of many neutral fans and just went to confirm the old adage: football without fans is nothing.
Forest fans to Arsenal's: “Champions of Europe, you’ll never sing that”. Arsenal fans to Forest's: “Champions of Europe? You weren’t even born.” #NFFCvAFC
