19 year old Colwill makes Wales Euro 2020 squad
The uncapped player has played just 190 minutes of senior football for Cardiff.
Rubin Colwill is the surprise inclusion in Wales' Euro 2020 squad, having played just over 190 minutes of senior football.
The 19 year-old Cardiff midfielder is among the group of 26, which also includes Gareth Bale, Aaron Ramsey, Ethan Ampadu and Joe Rodon.
"He’s been a breath of fresh air since he’s come in,” Page said of the uncapped midfielder who began the season playing academy football.
"He just blew us all away with how he was and how he conducted himself. He’s a top professional already and a great lad to have around the place.
"He’s really impressed me, he’s got a presence and maybe something we’ve not got in the middle of the park.
"He can play off the right, he can play as a 10, he can play in midfield – and that’s a bonus as well when you’re looking to pick a squad."
Daniel James has also been called up as expected after missing the training camp due to Manchester United's Europa League final.
Wales have warm-up games against France and Albania this week before beginning their Euro campaign against Switzerland in Baku on June 12th.
