Ynystawe-born defender Matthew Blake has been part of the Swans academy since he was eight years old.
The left-back signed his professional contract after breaking into the under-23s side during the 2017-18 season.
Despite back and quadricep problems, Blake made 13 appearances for the development side the following campaign, scoring his first goal in a 2-2 draw away at Arsenal.
After signing a new two-year deal in the summer of 2019, he played a further 15 times for the under-23s in 2019-20.
Blake regularly appeared for the development side during the first half of the following season, while captaining them on numerous occasions.
