Holgate scored his first goal for Everton in their development side's 3-1 win over Norwich City, as he continues to acclimatise to life at Goodison Park, after joining from Barnsley.
The young defender has played in a number of different positions during his short time with the Toffees so far, but Unsworth insists that this will only aid him in the future.
"We were delighted for Mason to get his first goal for us," Unsworth said. "He was made up and I thought he played very well. It was the first time he’d played as the left centre-back and playing different positions will help his development."
Given their similar career paths, Holgate will naturally be compared with John Stones, who moved from Barnsley and became a star at Everton.
The Toffees played Stones at right-back and centre-back during his initial time at the club, and it seems that teaching their youngsters to be versatile is a tactic the Merseyside outfit like to adopt in their nurturing of promising talent.
Holgate played most his football at Barnsley in the centre-back position, but his athleticism means that he is able to fill in at full-back.
That could aid him in his search for first-team football at Everton in the future, but for now it seems that his development will continue to be served with the under-21 side.
