Real Madrid is I think a very, very dirtily operated club. And that includes how the current stock of players act on the pitch. Dirty type of tactics. Very, very dirty. That was part of their STRATEGY in this game against Liverpool and that includes purposefully targeting players via pre-planned dirty plays. Extremely dirty things. No wonder they went for Mourinho and no wonder extreme dirt came out in his clashes vs. Barcelona while Guardiola was there.
One of the things I like about Guardiola is that he is a great manager/coach who focuses and wins through that stuff; through actually managing and coaching + football strategy. I've never noticed him planning and executing dirty things and then cheating like that.
