Denmark produce first shock of Euro 2012

Denmark provided the first upset of Euro 2012 when they beat Netherlands 1-0 in Kharkiv today in the opening game of Group B to leave the Dutch in a perilous position.

With Germany and Portugal, who meet later in Lviv, completing what is regarded as the toughest group at the finals, Netherlands have little margin for error after Michael Krohn-Delhi's goal earned the Danes victory.

Dutch 18-year-old Jetro Willems became the youngest player ever to take the field at a European Championship but it was to be a losing debut as Denmark sealed a first win in open play over Netherlands since 1967.

It will revive memories of their unlikely triumph at the finals in 1992 when they arrived as rank outsiders but went on to lift the trophy in Sweden.

It also serves as a warning to the rest of the so-called favorites and backs up Italy goalkeeper Gianluigi Buffon's claim that the "best don't always" win as he prepared for his side's opening match against holders Spain tomorrow

The second day of the tournament switched across the border from Poland to co-hosts Ukraine and, while there was again much to admire on the field of play, there were slight concerns off it with the first reports of crowd trouble.

Security organizers confirmed that four stewards had needed hospital treatment after being attacked by Russian fans in the stadium after the Russia-Czech Republic match on Friday.

"Such things can occur over the next 22 days. If it gets hot, drinks will be consumed and such things can happen. It's a normal situation," said Marcin Herra, head of the Polish company in charge of coordinating the finals told local television.
