Which of Everton trio that signed new deals has the most potential?

Everton were given a triple boost yesterday as Dominic Calvert-Lewin, Jonjoe Kenny and Mason Holgate all signed new long-term contracts with the club.
As reported by the club’s official website, striker Calvert-Lewin has signed until the summer of 2023, with defenders Kenny and Holgate committing their futures until the summer of 2022.
All three players look to have bright futures at Everton, but which of them is the biggest prospect?
Calvert-Lewin, part of the England squad that won the U20 World Cup this year, has impressed since joining Everton from Sheffield United in 2016.
A hard-working striker, he has scored twice in the Premier League this season, while he has provided six assists.
Although he is still rather raw, the 20-year-old is an excellent prospect and will surely develop further under Allardyce’s guidance.

Kenny, meanwhile, has featured regularly at right-back for Everton in recent weeks, helping to reduce the impact of Seamus Coleman’s continued absence.
Impressive defensively and also capable of providing a threat going forwards, Kenny, who is a product of the Everton academy, has been playing with increased confidence of late.
