I guess it's all about Ronaldo. If you foul Ronaldo you get a yellow card. Foul him twice and you are out. Amazing how it happened to Martinez who should know better. Ancelotti took out Xavi Alonso a few minutes later to prevent a second yellow / red card for another Spaniard.
Without a special Neuer performance, the result could have been 4:1 or 5:1.
Amazing what a red card can do.
BTW, am I the only one who thinks Carvajal was offside before he played the Cross that led to Ronaldo's first goal?
All replays showed Cr7's connection with the Cross, but I have not seen replays of the pass that enabled Carvajal to be completely free and by himself before crossing. Alaba must have been sleeping.
Anyway, water under the bridge. Bayern looked ok in the first half, even capable of scoring another goal (obviously Vidal's penalty + a perfect oppty for Müller disallowed by the referee because of a FALSE offside), but when Ronaldo scored and forced the red card, the game was over. Robben was still trying, but there was no Lewandowski in the center to help him.
Amazing, how similar the Bayern breakdown was to the Arsenal breakdown in the previous round. It is not easy to play quality opposition with 10 men!
Lesson learned: don't foul Ronaldo twice or FIFA will come after you.
