Bayern Munich have thumped Barcelona 4-0 in the first league of their Champions League Semi final. I have included the highlights below for those of you that missed it. I thought Bayern would win this one, but I never thought 4-0 but I suppose the signs have always been there. Barcelona's defence is just terrible. They are all about the attack and their left and right backs are not in the side for their defending ability. So I really don't see a way back for them. Thomas Muller netted twice, Arjen Robben and Mario Gomez also scored to hand Bayern Munich a famous win over Barcelona at the Allianz Arena.
