"This is a dream come true for me and also for my parents who are delighted for me. It's a tremendous league to be a part of, the Premier League, and we want to show that Aston Villa can take its place among the top teams.

"The manager is trying to create a new generation, to build something here and make a lot of young guys show what they can do. I'm up for the challenge.
"For every player who's coming in, it's good to find themselves in a team and an environment such as this. We will get the opportunity to show that we want to play and what we can do. It's always good to try to better yourself."
