Keita must think all his lucky days have come at once with the RS after his disgraceful disciplinary record in Germany... even 4 reds in one season alone. Hes not the only one living a charmed life with UK refs as you say. In addition to those, I'd add on Arnold, Van Dyck, Milner who throw their weight around illegally but seemingly without even a word off refs. That Konate fella will probably join that unspoken list too.
I've said it before, I wish someone would call them out on this in the media or do a compilation of the ones they get away with. Of course, their national treasure status remains untarnished with the media sheep so like "The Kings New Clothes", noone in the press/TV would dare.
