Borussia Dortmund and Real Madrid have headed into the half-time interval of their Champions League Group D clash in Germany locked at 1-1.
The first chance of the game fell to the Spanish champions in the sixth minute, when Cristiano Ronaldo drilled in a cross from the left flank only for Mesut Ozil to in making contact with the ball.
Seven minutes later Dortmund went close, Sebastian Kehl forcing Iker Casillas into making an important save, and then Robert Lewandowski shot Marcel Schmelzer's left-wing cross over the crossbar.
Madrid, though, soon started dominating proceedings at the Signal-Iduna Park, and could have taken the lead in the 23rd minute had Angel Di Maria not shot over the Dortmund crossbar from a good position.
Three minutes later Ronaldo failed to keep his attempt on target from the left side of the German champions' penalty box.
However, Dortmund refused to allow Jose Mourinho's side to call all the shots, with Kehl testing Casillas with a brilliant curling effort from 20 yards.
Jurgen Klopp's broke the deadlock much against the run of play in the 36th minute, Lewandowski clinically turning home Kehl's ball from close range after taking advantage of a mistake from Pepe.
However, the German champions' lead lasted just two minutes, as Ronaldo latched on to a precise through ball from Ozil before lifting it over Roman Weidenfeller and into the Dortmund goal.
