Viktor Gyökeres fired home his first Arsenal goals in a thumping 5-0 Premier League victory over Leeds at the Emirates.
Jurriën Timber opened the scoring from a corner after 34 minutes before Bukayo Saka doubled the home side's advantage on the stroke of half-time.
Gyökeres bounced back from missing a sitter in the opening period to score on his home debut three minutes into the second half and Timber then landed his brace shortly before the hour mark.
Max Dowman, aged 15 years and 234 days, delivered an impressive second-half cameo from the bench when he became the second youngest player to represent Arsenal, and the teenager capped an eye-catching display by winning a penalty for his side in stoppage time, which Gyökeres duly converted.
