“It does worry me a little that the aggression was missing on Sunday. I wanted it from the very beginning.
“We have a principle and this week I am going to work on it a lot – we call it the 10-second principle.
“If you start with the ball, or your opponents start with it, then you need to create some sort of danger within the 10 seconds.
“The ball must be closer to the opponents’ goal or, if the ball starts with the opponent, then you must recover the ball within the 10 seconds.
“Did you see that in the last match? I don’t think so.
“We need to be angry about that and, because it is an Old Firm game, we need to feel shame about it because we didn’t perform.
“We didn’t have the passion that this club is giving to us. I want my team to have a different sort of commitment, to have a different level of concentration and a different competitive attitude.
“We prepare the team to be aggressive and we want the team to be aggressive in a good way for the whole game. You can’t even have 45 seconds where you are not focused.”
