Duncan Ferguson has been hailed for the transformation of Dominic Calvert-Lewin during his spell in caretaker charge of Everton.

Speaking exclusively to Football Insider, ex-Leeds United and Coventry City striker Noel Whelan claimed the forward has been turned from “average” into a “world beater” during the space of a few weeks.

Calvert-Lewin, 22, played the full 90 minutes of all four games under Ferguson, including in today’s goalless draw against Arsenal.

The striker netted twice in the 3-1 win over Chelsea to take his goal tally for the season to seven from 20 matches in all competitions.

“You look at Calvert-Lewin and he’s a different player,” Whelan told Football Insider. “More physical, more dominant, holding the ball up and really working defenders. He’s not scored loads of goals but he’s a real handful.

“He’s really brought into Ferguson’s methods and all credit to both of them. I’m almost stunned at the turnaround.

“Ferguson has transformed him from average into a world beater in a very short space of time.

“Calvert-Lewin will be disappointed he hasn’t got the job on a full-time basis.

“He might not be the only one, either. Everton look more committed, more tenacious and far harder to beat than they were under Marco Silva.”

Calvert-Lewin has made 112 appearances for Everton since signing from Sheffield United in the summer of 2016.

The former England Under-21 international has scored 24 times and supplied 10 assists for the club.
