It had been a subdued night in Monaco, with Manchester City sleepwalking to victory until Nico González kicked Eric Dier in the face in a failed attempt to defend a free-kick. Chaos ensued with a melee as City lost their cool and the chance of a perfect Champions League start, before Dier calmly slotted home a last-minute penalty.
City have only themselves to blame for not finishing off a stubborn Monaco off earlier. Erling Haaland proved there was such a thing as a sure bet as he increased his club tally to 11 goals in eight games, only to have his work undone by two incidents of poor defending.
