Thing is that you can hardly deduct something from stats like that. Same as "oh but they got 10 penalties this season whilst we only got 3", means nothing because you have to look at each situation individually.Liverpool: 14 fouls, 1 yellow.
Brighton: 4 fouls, 2 yellows.
And these scouse cnuts actually had the front to boo the ref at half time like they're being hard done by.
That said, he should've said to Diaz a long time ago that he needs to tone it down or the next one would be a yellow.
