The first half of the match is ended and let's assume that Real Madrid's agony is ended. The beginning of the second half could birth a new opportunity for Real Madrid to turn things around. Besides, a stable Real Madrid might not find it difficult to come back. But with the crop of Real Madrid players that I am seeing now, it is near impossible to do.
From what I witnessed in the first half, Real Madrid was totally out of the game and PSG missed a very good opportunity to score the 4th goal but the ball was like a meter away from the box.
The defence line of Real Madrid was very vulnerable and not that concentrating especially on counter attacks. They were lucky PSG player didn't pass the ball to his colleague at his right and they didn't commit a fault when catching the ball from him, otherwise it would be another opportunity to add a goal.
Xabi Alonso should change his tactics in that game or he will lose it badly..
