Asked if he has given Jackson any specific advice, Maresca said: "Continue to work in the way he’s working. He scored many goals at the beginning of the season, now there are games he's not scoring. We are completely happy, we don’t judge Nicolas because of his goals but different kinds of things. Last year he scored 14, 15 goals in the league without penalties - Haaland, Salah, Palmer take penalties.
"If you score 14 or 15 in Premier League and add penalties, that’s a 20 goal striker. This year he scored nine or 10, with penalties that’s 13, 14. He’s doing well. Most of the nines shoot penalties so we are completely happy. For sure he’s going to score goals. In all the games he hasn’t scored he’s had great chances but sometimes you don’t score."
