Manchester City finally cracked the code at Tottenham Hotspur Stadium to seal a place in the FA Cup fifth round.
You could see exactly what it meant by the wild celebrations among around 9,000 Manchester City supporters who had made the Friday night trip to north London.
It was no more than City deserved for an impressive display that had pretty much everything apart from that end product, until Ake provided it with time running out.
Manager Pep Guardiola, who paid rich tribute to his great adversary Jurgen Klopp, after he announced he would be leaving Liverpool at the end of the season, was an animated figure at the final whistle.
Manchester City, with Kevin de Bruyne getting more match practice as a substitute and striker Erling Haaland on the way back from injury, look increasingly formidable and this win keeps them in the hunt for the FA Cup, Premier League and Champions League – the same treble trophy haul they won in such style last season.
