Bayern were at home and as often happens the home side had the bulk of the game. They had a lot of possession but Chelsea defended well and Bayern failed to score until quite late in the game. They then took off an attacker and put on another central defender basically trying to shut shop. The only needed to defend for a few minutes and manifestly failed to do so. A team can create as many chances as it wants but in the end it is about putting the ball in the back of the net. They both did that only once. Chelsea may have ridden their luck but they won fair and square.
