There is a difference between 'closing out a game' or trying to break the other teams momentum and parking the bus.
What Jose did at Anfield (and has done almost every time he has taken a team to Anfield) was parking the bus. I think Utd had 1 shot in the whole game and they barely even looked to attack. That is very different from, "we're 2 up let's see it out" or "right they are playing us off the park ATM, just sit in for 5 and get a foot hold in the game." The first of those implies you have at least tried to play/attack before, the second that you may have done and may well look to once you get over the next 5/10 mins.
Jose's bus parking, and he isn't the only one who does it, but he is the only manager of a 'big side' (that I can think of) who does it so regularly, is purely designed to suck any chances and by default entertainment out of a game.
It's a means to an end for him. His method of operation is don't lose big away games and grind out enuf points against the weaker sides that you win the league. TBF, it has worked for him. I don't think it'll work this year though.
For the record, Rafa was quite good at setting up Liverpool to be hard to beat/dull as, when we won the CL in 05. Though, and I admit I am biased, I will cut him a little slack as a team that has Djimi Traore, Igor Biscan, Sinima Pongolle and Bruno Nunez, is a tad different to the current Utd squad (or Jose's Chelsea/Real teams). Houllier also got Pool to a UEFA cup final by playing 4-5-1 and hoofing long balls to Owen. About as exciting for a neutral as a boot in the plums.
