The first time Myles Lewis-Skelly crossed his path, Erling Haaland demanded to know: "Who are you?"
Manchester City's superstar striker was unimpressed to be confronted by the Arsenal teenager at Etihad Stadium in September.
That first meeting came amid angry scenes at the end of an ill-tempered 2-2 draw at Etihad Stadium, during which Lewis-Skelly made headlines - before he had even played a minute of Premier League football - by being shown a yellow card while warming up as a substitute.
Haaland need not ask again. Lewis-Skelly, 18, inspired a 5-1 win that keeps Arsenal right in the title race - and delivered a goal celebration for the ages which appeared to be aimed right at City's striker.
