Manchester City boss Pep Guardiola has slammed referee Lee Mason after he revealed winger Leroy Sane picked up an injury in his side's full-blooded FA Cup tie with Cardiff.
Towards the end of the first half, Sane launched a blistering counter attack that came to a sudden halt when he was hacked down by Cardiff's Joe Bennett.
Replays showed the tackle was high and reckless and the impact forced the German's ankle to roll in uncomfortable fashion as Bennett escaped with only a yellow card.
Further enraging Guardiola, the defender then lunged in on substitute Brahim Diaz in the closing moments but this time received his marching orders.
