The England U20 international, who joined the Toffees from Sheffield United in 2016, quickly made the transition from the club’s reserve set-up to the first team, showing tremendous potential in his 11 appearances.
Were it not for a two-month injury lay-off, the 20-year-old forward could well have featured more regularly for Koeman’s side, given the Dutchman’s obvious admiration for his skill, versatility and temperament.
“He deserved to start matches last season and he is progressing well, but he needs to progress more because he is still only 20 years old,” Koeman told the club’s official website.
“He’s physically strong, which makes him a little bit different than the likes of [Tom] Davies and some of our other young players. He can play in different positions up front.
“He’s really improving in his movement and finishing, and that makes him a first-team player. But he’s a good boy who is serious and has a phenomenal attitude, which is what we like.”
Calvert-Lewin will start the Premier League campaign on a high, following his starring role in the England U20’s triumph at the World Cup. He capped off an excellent showing in the tournament by scoring the only goal in the 1-0 victory over Venezuela in the final.
