Striker Thompson, who finished as top scorer for the U23s, also made it as far as the bench at first-team level last season, having made his Premier League debut as a substitute at Manchester City in June 2020.
Thompson, 19, previously spent time at Everton and Manchester United – where defenders Gallagher-Allison and Dodgson (both 18) also started their youth careers before linking up with the Clarets last season.
Unwin, 18, also started out in the Academy setup at United before joining Burnley from Bury two years ago.
Goalkeeper Thomas has spent two seasons as a scholar with the Clarets after arriving from Manchester City.
And after graduating from the youth team to the U23 setup, the 19-year-old travelled with the Clarets’ senior squad for the final Premier League game of last season at Sheffield United.
Thomas is joined in the goalkeeping department by Allen, another former United junior, who has developed through a three-year scholarship with the Clarets.
And wingman Tucker – an 18-year-old Bermuda youth international – steps into the professional ranks after spending seven years coming through the Academy set-up at Turf Moor where the Clarets are continuing to nurture young players on a potential pathway to the Premier League.
