BERLIN - Real Madrid snatched a 2-1 comeback win after Christiano Ronaldo scored twice to beat ten-man Bayern Munich in the first leg of UEFA Champions League's quarterfinal on Wednesday.

The "Bavarians" were unable to defend their opener as Real turned up at the second half to turn the tides with two goals from Ronaldo on the road.

The visitors from Madrid ensured the first promising chance of the game when Bayern goalkeeper Manuel Neuer had to tip Karim Benzema's header on the bar with 18 minutes played.

Nevertheless, the opener was scored at the other end of the pitch as Arturo Vidal headed home a corner kick from Thiago Alcantara to break the deadlock seven minutes later.

Bayern should have doubled the lead before the break but Arturo Vidal was unable to convert a handball penalty in the dying minutes of the first half.

Real Madrid punished Bayern's wastefulness after the restart as Christian Ronaldo restored parity after volleying home a cross from Daniel Carvajal with two minutes into the second half.
