Tbh there were plenty of reckless tackles made in that game more so from United. Neville could of easily been off if Ballack had gone down. He literally flung himself in there, Rio @ the end on Drogba.
I think United were frustrated in the 2nd half, chelsea were the more dominant and the United back 4 were under pressure and under attack for most of the 45. This frustration i reckon showed in the tackles that were being made.
Still though Riley is a bell... Always has been and always will be...
I do not mind seeing the boot being on the other foot with united, i can think of many many moments that it has gone in there favour. Mascherano, Wigan end of last season. Mikel @ Old Trafford...
