It's similar to what alot of idiots on here do though, see the Firmino thread for an example of the whole "I was right, I am amazing" bullshit that lacks any sort of actual perspective or humility. It's the same daft twats time and time again who repost old threads to give themselves a pat on the back about a subject. I mean really, like there's anyone on here who's never been right about something, or wrong about something else.
The urge to blow ones own trumpet and big up personal achievements usually masks some incredible insecurity. Mourinho must have some fucking massive insecurity.
