Pickford has made 329 appearances for Everton since joining from boyhood club Sunderland.
He has played a major role in helping Everton retain their Premier League status despite managerial sackings, financial rule breaches and points deductions in recent seasons.
He has won 79 caps for England and has been first choice for the Three Lions since the 2018 World Cup.
Pickford broke a long-standing record set by Gordon Banks last week by recording an eighth consecutive clean sheet in the Three Lions’ 3-0 win against Wales.
He last conceded a goal for England more than a year ago, in a 2-1 Nations League defeat by Greece.
