Good analysis here on the tactics of Simeone vs Guardiola.

I prefer Guardiola personally as it is more in tune with the beautiful game and I was actually pleased to see Manchester City frustrate Athletico, the same way that Athletico try to do it to other teams and in the end they could not take it and buckled a bit in the closing stages. Yes, they had chances, but they allowed themselves to get too wound up and in the end, they beat themselves in my opinion.
