Czechs hold Denmark
The Danes created several chances but lacked bite without striker Nicklas Bendtner who was serving a one-match ban for revealing a betting company logo on his underpants at Euro 2012.
The home side's best chance of the opening period fell to Michael Krohn-Dehli, who fired wide after chesting down a cross from the right in the Group B encounter.
Moments later, Dennis Rommedahl nodded wide as he tried to loop his header from Krohn-Dehli's pass over keeper Petr Cech.
Denmark continued to press in the second half, with seasoned winger Rom-medahl tormenting the Czechs with a succession of dribbles, crosses and shots.
The Danes were also denied a late penalty.
