Wales interim manager Rob Page hailed Brennan Johnson as a "wonderful talent" after his late goal earned a draw against Belgium in the Nations League.
The 21-year-old's first international goal four minutes from time rescued a point for Wales after Arsenal-linked Youri Tielemans had opened the scoring at the Cardiff City Stadium.
"There's more to come," Page said of Johnson when asked about his equaliser after the game. "He's a wonderful talent, I'm looking forward to watching him in the Premier League next season and watching him grow with us.
"Every time he comes on he impresses and shows his worth, he's deserved his goal and he's got a lot more to come."
Johnson's rise to prominence has coincided with Nottingham Forest's return to the Premier League after a 23-year absence, with his standout performances in the Championship helping Steve Cooper's side reach the play-offs, where they downed Sheffield United and Huddersfield Town.
Page admitted that there are areas of Johnson's game that can be improved and worked on, but stressed that no team in the world would want to see him climbing off the bench late on in a game.
"We chatted with him yesterday and showed him clips on where he can improve and get better," Page continued. "When players play a certain way at club level, that's not necessarily how we want to play, it is about him being adaptable, there was nothing about making him a better player from a technical point of view.
"It's about giving him the most opportunities to create chances.
"When Brennan comes on, depending on if we are chasing the game or not, I think he can drop into that 10 role like Gareth [Bale] does.
"He's done that for Nottingham Forest, but his main asset for me is his pace over the top. No defender in world football that would want to see Brennan Johnson coming on with 15 minutes to go."
