The 21-year-old has moved to the Clarets after spending five years at United.
The Tunisia international joined our youth system from Monaco in 2019, and has since gone on to make 13 first-team appearances for the club.
Hannibal became the 239th graduate from our Academy in 2021, when he made his first-team debut against Wolves, just three days after being named as our Denzil Haroun Reserve Player of the Year.
He scored his only senior goal for the Reds in 2023, netting from long range in a 3-1 defeat to Brighton & Hove Albion at Old Trafford.
In the 2022/23 season, the midfielder went on loan to Championship side Birmingham City, and he spent the second half of last term at Spanish outfit Sevilla.
After spending pre-season and the start of 2024/25 as part of Erik ten Hag’s squad, he now joins Burnley, who are looking to make an instant return to the Premier League under new manager Scott Parker, following their relegation last term.
We wish you the best of luck with your next steps, Hannibal!
