Referee Stats

Don't use them myself, but if you scroll down a little here's a few that might interest you...

But pretty much need to factor in new increased leniency

Thanks, lads already very informative.

Mike Dean "The Penalty King"
Howard Webb "Never Gave a Thing"

I don't study their stats (though should I'm sure do so and am on my own admission a mug when it comes to football), but I do like to back red cards when the ref is either Michael Oliver or Anthony Taylor. They are also top drawer officials, I love the way when players get in their faces or surround them (despite wearing pointless "respect" armbands), both refs, Oliver in particular, look at them with absolute disdain. Result is that most such players walk away with their tails between their legs. Mike Dean was also great with the disdain look.

Mike Dean never reffed Champions League or international tournaments because he wasn't good enough, just a gawky, theatrical showman

You're entitled to your opinion of course, mesmerised, but some might argue that if he was as you describe, he provided more entertainment than some of the overpaid prima donnas he had to keep in line every match. Personally, I was and am always more inclined to watch a game officiated by any of Messrs Oliver, Taylor (Jack and Anthony), Dean and naturally "THE man", Graham Poll.

The best referees are the ones you don't notice.

Mike Dean was a great referee.  If he thought it was a pen he gave a pen.  Imo the only top PL referee who had the bottle to do that.
