BR - The UEFA Champions League is not for the faint of heart.
Consider the stress endured by Manchester City fans who watched as their team blew a 2-1 lead to Real Madrid in its opening match and lost 3-2.
Or how about the sheer talent on teams such as Barcelona and Manchester United?
The tournament has only just begun, but many teams are already facing must-win situations if they have any hopes of advancing to the knockout round. Others are sitting pretty after opening the tournament with a victory.
