Kai Havertz appreciates better than most the value of a goal on the big occasion and the way it can alter perceptions.
Take his last three for Chelsea, the first in a big European tie, a nerveless late penalty to claim the world title and the opener in a Carabao Cup semi-final to set up tomorrow's date with Liverpool at Wembley.
He has developed a happy knack but the one that secured his place in history and in the hearts of supporters at Stamford Bridge came against Manchester City, the only goal in last year's Champions League final in Porto.
