The talented 20-year-old attacking midfielder has committed himself to his boyhood club and is delighted to continue on at a place he describes as 'home'.
"Everyone knows this is a club I love dearly - and it's the place I want to play my football," he told Villa's official website.
"Bodymoor Heath provides a great environment in which to continue my football education and to call Villa Park home is something I will never take for granted.
"We're looking to return to the Premier League. I want to be a big part of that process and will be doing everything possible to make that a reality."
So happy to have signed a new 4 year contract. It's an absolute pleasure every time I put on this shirt! #AVFCpic.twitter.com/vzlbeNrEUx
