Well you tell me how an elite professional referee (supposedly) 12 days apart, can give such wildly different decisions for the same range of offences, and before you refer to "maybe he got told off", why wasn't it corrected after he let Milner off? Why is it only against City these offences aren't punished game after game, yet suddenly tonight he's punishing them with glee?
Paul Tierney's fouls per tackle average this season is 0.64.
His fouls per tackle average for Liverpool's opponents is 0.91, for City is 0.43, so less than half for us. Liverpool's opponents on average also get double the number of yellows per game (3.67 vs 1.8)
