Brighton manager Roberto de Zerbi didn't know who Joao Pedro was when the club spent a record £30m on the Brazilian in the summer.
Seven months on, the former Watford striker is up to 15 goals for the season with his second-half double in the 4-2 FA Cup win at Stoke.
Of Premier League players, only Erling Haaland (19) and Mo Salah (18) have scored more this season. He is level with Glenn Murray's club tally from 2018-19, with only Michael Robinson ahead of him in a Brighton season as a top-flight club with his 22 goals in 1980-81.
