Who is new Leeds United signing Amari Miller?
Amari Miller is a winger who has risen through the Birmingham City academy ranks.
The 18-year-old joined the Blues on a two-year scholarship in July 2019 and has quickly progressed and drawn attention from a number of teams.
Miller featured in Birmingham's pre-season friendlies at the start of the 2020/21 campaign, making four appearances before the term got underway.
He spent the majority of the season playing in the club's academy but was handed a chance by head coach Lee Bowyer in the Championship towards the end of the campaign.
Miller was called into the senior squad for the first time in April and was introduced in stoppage time against Stoke City for his first team bow.
The wide man made two more substitute appearances for City before Bowyer opted to hand him two starts after safety was secure.
Miller was offered a professional deal at St Andrew's in May but has opted to turn the contract down in favour of a move to West Yorkshire.
What has been said about Amari Miller?
According to former academy manager Kristjaan Speakman, Miller is: "A creative player, able to stay of the ball and dribble with speed and changes of direction. He is an attacking player who is exciting to watch and one the players enjoy playing with due to his flair in possession."
Lee Bowyer said of his abilities last month: "[He adds] Goals, assists, pace, something that we probably lack a bit is pace. He’s at that age where he is fearless. When he came on against Stoke, he got himself into an area and wasn’t afraid to go at the defender.
“I think he will be a good player. He just needs to keep working hard. Hopefully, this taste that he’s having will drive him on for next season.
“I like him as a person, his manners and he’s respectful. The senior players love him as well. He’s going to make mistakes, but he keeps going. He’s fitted into the group well."
