Our legendary former midfielder - always remembered for his last-minute winner in the 1999 League Cup Final - helped take the Danes to the quarter-finals in France in 1998.
Along the way, Denmark faced hosts and eventual-winners France with Allan finding himself up against Petit/Vieira/Karembeu/Djorkaeff before a quarter-final with runners-up Brazil and Duna/Rivaldo/Leonardo.
Now another midfield clash all Spurs fans are relishing - our Great Dane Christian Eriksen up against former Spur Luka Modric in Nizhny Novgorod (7pm UK).
