Manchester City were more relaxed on the ball, i watched them play right from the start of the game, the way they handled the ball feeling relaxed no pressure to force an attack, they held the ball too well but times when they should have quit the passes and find goals they lack seriousness. Doku is the only player with some of the young players who dealt with Liverpool, his performance was striking, he gave everything he had just to make sure the teams succeeded but the rest players never understood from him.
I don't agree with you that Manchester City was so relaxed because they even made more attempts on the goalkeeper than Liverpool did so the only reason why it looked like they were more relaxed was because they possess the ball more while Liverpool capitalized more on counter attack that is why Liverpool could score two goals before halftime while Manchester City was making passes. Manchester City played more of a matured football while Liverpool was more targeted at scoring goals without keeping the ball for a long time in the possession. Doku is indeed a superstar and if the rest of the players made efforts as Doku did, they could have at least scored one goal even if they don't equalize.
