Manchester United U23s coach Neil Wood has sung the praises of Hannibal this season.
The 18-year-old is viewed as an attacking midfielder who can occupy positions across the three forward positions behind a centre forward, although Wood says he has played Mejbri deeper at times to instil discipline into his game.
"I think he's been on an incredible journey really," he said. "When he first came up, he was full of energy and was running everywhere, sometimes to the detriment of the team.
"His discipline has improved greatly, on and off the ball, and his defensive responsibility. He's really starting to understand that a little bit more.
"It was difficult at the start as the physicality was a step up for him but he's a tough kid. I think he can take the knocks and can look after himself.
"I feel it's important he has a few positions he can play in and a few positions he can excel in and make an impact, rather than just be a no. 10 or a higher midfielder.
"It's important, at times I'd drop him into a lower midfield role to see if he could play with a bit of discipline, could work hard, tackle and get on the ball and build up momentum and be sharper. He played left, no. 10 a bit of a false 9, a free role, dropping in between to take up positions.
"There have been a number of challenges, different challenges, but I think, on the whole, he has done very well with it."
