The Rochdale-born winger joined the Clarets' Academy system in 2014 after leaving Manchester United.
He was rewarded with a two-year scholarship in July, 2016 and became a regular member of the under-18 side, as well as appearing for the Development Squad.
A leading performer for the Under-23s in 2017/18, McNeil was named as the Clarets' Young Player of the Year and rewarded with a first professional contract in April, 2018.
He also got a taste of first-team football with a Premier League debut as a substitute on the final day of the season.
And he then became a regular in the senior set-up during 2018/19, making a full debut in the Europa League in August, 2018 before a first Premier League start against Manchester United a few days later.
His first senior goal came in a 2-0 win over West Ham at the end of 2018 as he started an uninterrupted run of games to the end of season, playing a key role in the Clarets' Premier League survival.
His performances were rewarded with a new long-term deal in January, 2019, with the wideman signing a contract until June, 2023, with the option of a possible further 12 months.
And following a first call-up to the England Under-20 squad in March, he was again selected for the summer Toulon Tournament to cap a break-through season for the highly-regarded winger.
McNeil duly earned his first call-up to the England U21s in the autumn of 2019.
His first cap came in a European qualifying tie in Slovenia as McNeil went on to enjoy an outstanding 2019/20 season.
The winger was an ever-present in the Premier League and played a leading a role as Sean Dydche's men secured a top-10 finish.
With six assists, McNeil jointly led the way for the Clarets alongside Ashley Westwood.
