CARRAGHER: When we played in Europe under Rafa, we could attack, we could counter-attack and other times we would just defend - even at home. Last year, Madrid surprised Bayern by playing on the counter-attack. Here with Guardiola, every game he has a plan. How important is it to have different ways of playing?

ALONSO: Each team I see (that is successful) has to be comfortable playing with three systems. They need to adapt to each game, depending on the circumstances. It is not about not being loyal to your identity. No, no, no. It is about knowing your strengths and showing your players what you need to do each game to prepare in the right way. In Liverpool, we had a plan for each team. Every game is totally different. Let me give you an example. This season we have played with three defenders, sometimes four, sometimes five. You need to be able to manage at least three or four systems. It has nothing to do with betraying your principles.
