Princess Alexandra of Denmark will be among the fans cheering on the national side in Sunday's quarter-final at Porto's Estádio do Dragão against the Czech Republic.
Denmark qualified as runners-up from Group C and are unbeaten in their first three games of the tournament. They had royal backing for those games, from Crown Prince Frederik's younger brother Joachim, who congratulated the players in their dressing room after each of the games.
Denmark's royal family are hugely popular: more than half of the country watched Frederik's wedding to Australian Mary Donaldson this May. A similar number of Danes will watch the quarter-final against a talented Czech side, while nearly 6,000 Danish fans will be cheering them on in the stadium.
Thanks from mayor
Meanwhile, the mayor of Guimarães, Dr António Magalhães, has publicly praised the Danish fans for their behaviour before and during Denmark's opening match against Italy, which finished 0-0.
In a letter to the Danish ambassador in Portugal, Magalhães wrote: "Please allow me to congratulate the people of Denmark for their worthy and decent behaviour on 14 June and the days around that date in Guimarães in connection with the match between Italy and Denmark."
Friends in Guimarães
The letter continued: "The joy, the excitement, the public displays of support – all very well-behaved – of the Danish fans made such an impact on the Guimarães people, that the locals have since been worrying about their Danish friends' results in the matches to come."
