Manchester City boss Roberto Mancini accused Liverpool of poor sportsmanship after their 2-2 draw. The Reds refused to kick the ball out while Edin Dzeko lay injured and former City man Daniel Sturridge smacked in the equaliser.
He said: "They should probably have stopped. Dzeko was on the floor, we didn't know what had happened.
"After this foul we had 15 seconds before the goal but this can happen.
"For the first goal, I'm disappointed. If Vincent Kompany did that, it'd probably be a red card but the ref gave nothing.
"The linesman for 10 minutes saw everything for Liverpool but he didn't see this. Refs are making mistakes every game."
