Jay signed from Luton Town as an Under-13 and is an attacking left-back who is equally capable playing on the left wing, a position from which he scored in the FA Youth Cup final in 2014.
He made his youth team debut as an Under-15 in 2012/13 before his breakthrough the following season in which he played 23 youth team games, including starts in both legs of the Youth Cup final and an Under-19 debut.
Quick and strong, despite his slight build, Jay excelled in his first months as a scholar and quickly progressed to become an Under-21 regular. He played in every game of the triumphant Youth Cup campaign and all but one game as the Under-19s were crowned European champions.
An England Under-19 international, he signed his first professional contract in July 2015.
In 2015/16, Dasilva established himself as a vital part of the Under-21 starting team while also finding a goalscoring touch. He netted in the Youth Cup in ties against Huddersfield and Reading, while also scoring our only goal in the UEFA Youth League last-16 win against Valencia.
The youngster tasted success in both competitions once again, lifting the Youth Cup for the third time and joining the record books along with teammate Jake Clarke-Salter. The duo join five of Manchester United's Busby Babes side in claiming the personal accomplishment.
Having made 16 appearances for our development squad team in the first half of the 2016/17 campaign, Dasilva moved on loan to League One Charlton for the second half. He came on as an early sub in a local derby against Millwall in his first month there and while he had to be patient, the left-back forced his way into the side and performed well in the final few weeks of the campaign. He made 10 appearances for Charlton by the end of the season, and returned to the Valley for 2017/18 fresh from signing a new four-year contract at Chelsea.
