Mason Holgate joined Everton on 13 August 2015, moving from Barnsley for an undisclosed fee.
Holgate, who can play at centre-half or right-back, was handed his professional debut by the Tykes in December 2014 and went on to make 20 appearances in League One that term, as well as a further two in the FA Cup.
The defender's first season on Merseyside saw him put in a number of solid performances for the Club's Under-21s and he was duly called up for the first-team's pre-season training camp in Austria in the summer of 2016.
After an excellent pre-season, Holgate was rewarded with a senior Everton debut against Tottenham Hotspur on the opening day of the 2016/17 campaign.
He enjoyed an impressive term, figuring as the right-sided centre-back in a defensive three or at right wing-back, before playing every match of England Under-21s' European Championship campaign in summer 2017.
Holgate came to the fore in 2017/18, becoming a regular in the Everton's first team and producing a string of commanding performances.
His accomplished displays were rewarded in December 2017 when he agreed terms on a new four-and-half-year contract with the Club.
Having made 21 first-team appearances - of which 19 were starts - Holgate's season was curtailed when he was forced to undergo ankle surgery in March 2018.
Holgate started the following campaign by featuring in Everton's opening five Premier League matches.
He continued his development with a loan period at Championship side West Bromwich Albion, excelling at right-back and playing 21 matches as the Midlanders reached the play-offs before going down to a penalty shootout defeat by Aston Villa.
The defender returned to Everton for the 2019/20 season and emerged as one of the key players in manager Carlo Ancelotti's side, being rewarded for his impressive displays at centre-back with a new five-year-deal in March 2020.
Holgate finished the season with 32 appearances - 29 starts - in all competitions and established as a significant figure in Italian Ancelotti's long-term plans.
Contracted until: June 2025
