It was all going so well.
Manchester City had 74 per cent possession in the first half, had dominated a very good RB Leipzig side, and done so by fielding another innovative formation without two of Pep Guardiola's best players. But then it all unravelled, and the frustrations couldn't be hidden at full time. They had been creeping in for a while before.
After an impressive Leipzig fightback, City felt aggrieved by full-time after a late penalty shout went ignored, and Guardiola felt compelled to begin his post-match team-talk on the pitch. Erling Haaland had started to turn on teammates, leaving an evening that started with such promise with something of a sour taste.
