Is SAF really so good....?

... he became the coach of Man U in 1986 and his first league title was in 1993... after SEVEN years... and his first CL trophy was in 1999... lol... after 13 years..... let me remind you that Mourinho won league title in his first season (and second right after first one) and that he already won CL with Porto, a club that is not as half as rich as Man U.... or Rafa that won the CL in first season too and this is only his 5th season.... SAF didn't have NOTHING (one FA Cup) in his first SEVEN seasons... heheheh.... and even Wenger won 3 league titles and 3 FA Cups already in his first seven years... so please explain me by what logic is SAF so great because the way I see it if Mourinho didn't leave Chel$ki would dominate EPl just like Man U did in the '90!!!!
