Honestly I always see Real Madrid as the top favourite of this competition. 15 titles in total and many of them were achieved in last 10 years.

They are always a serious threat to all other clubs here.
Now they've entered a new path with Xabi Alonso. He is experimenting with the players for now. Trying to solve the issue of selfishness in the attacking area. Once he figures it out I believe in them to fight for another CL trophy with all they've got.
