Which football fans sing the praises of players from different clubs?

“Do any fanbases regularly sing in praise of a player who never actually played for them?” tweets Andy Brook. “Possibly due to scoring a vital goal against a rival or something similar?”

The key phrase here is probably “in praise”. A number of you mentioned schadenfreude-fuelled chanting – Steven Gerrard’s slip, Patrick Vieira giving Giggs the ball, that kind of thing – but you could write a book on those and they aren’t really in the spirit of the question. So let’s focus on the positives.

Unless you’re a Hearts supporter. In May 1986, Dundee striker Albert Kidd became a hero at two other clubs after a decisive intervention in the title race. “Kidd came off the bench to score two late goals against Hearts in the final league game of the season, thus handing the title to Celtic after the Jambos, unbeaten since September, had been two points ahead with a four-goal advantage and seemingly nailed on for the title,” writes David Forbes. “King Albert is revered by Hibs fans, was voted Hibs’ player of the season by some and, if memory serves correctly, there is, or was at one point, a Hibernian supporters’ club bearing his name. I still enjoy the memory, and I’m not even a Hibs fan.”

As you can imagine, Celtic fans are equally fond of Kidd.

But they were less enamoured with Scott McDonald, when his two goals on the final day of the 2004-05 season denied them the title. McDonald became a Rangers hero – and, later, a Celtic one when he joined the club and banged in 25 league goals to help win the title in his debut season.
