With just days before they face Bayern Munich in the Champions League Final at Wembley, Borussia Dortmund have officially kicked off the mind games by invoking one of the Bavarian side's most painful memories in their museum.
BVB have put a Manchester Utd jersey belonging Ole Gunnar Solskjaer on display. Bayern fans will need little reminding that the plucky Norwegian scored the winning goal in the 93rd minute of the 1999 Champions League Final, in one of the biggest upsets in football history.
It is not actually the garment the Baby-Faced Assassin wore in the '99 final, but one he swapped with Dortmund's Knut Reinhardt after Utd's European Cup semi-final defeat of 1997.
So technically, this is an authentic piece of memorabilia to place in their museum. But they don't exactly have to rename this part of the building "The Didier Drogba Memorial Wing presented by Porto" to make it clear they are trolling their Bundesliga rivals for their predilection for losing European Cup finals in the dying moments.
