Why do you suppose that you can speak for all Bluemoon posters? Do you read anything other the United thread?
Mourinho won the PL in his first English season didn't he, so why should Pep not have a realistic chance?
The only people I have heard referring to Pep as "The Messiah" are Reds. Can you give me a link to where you've read a Blue using that phrase?
Simple answer to that is he can't present any evidence of the above being applicable to all BM posters. Maybe he thinks he's in the Bluemoon meltdown thread coming out with his sweeping generalisations - the only thing that's missing is a reference to his sparring partner manimanc.
