Meh, I'm largely ambivalent about it all, to be honest. I like Mourinho, but I do agree that the constant framing of everything from the British media as Mourinho vs whoever is more than a little embarrassing. The fact that they don't do the same for anyone else suggests that many in the British media have been seduced by something other than football. Even if you like him, as I do, you still have a duty to be objective in your reporting and your assessment of the game and his abilities, and the constant focus on one man is totally unprofessional, in my opinion.
I also love the way that Barca approach the game, but as someone who would usually rate them as probably the classiest club in world football, some of their antics were extremely classless.
As to the way in which Inter won the tie, there are several ways of looking at it. To remain (largely) consistent, while I don't like it when United approach games like that — which is very rarely, thankfully — I will usually accept it on the odd occasion if it gets us through an important game (like the Semi-Final against Barca). So, I can't then complain about another team doing it, unless I can show that it is somehow different.
On the other hand, I have to admit that the game would be incredibly dull if all teams approached games like that, whereas it wouldn't be if every team approached games like Barcelona. However, the fact that there is such a range of approaches is largely what makes the game so intriguing.
I do admit, though, that when lesser teams attempt to do that against United, it does annoy me, and I take more satisfaction from beating them. Whether you believe that some teams "have little choice" or not (which is almost always untrue, anyway), the game simply wouldn't be so popular if every team approached it in that way. That's undeniable, even if you also believe that the game benefits from a variety of approaches.
