The Manchester United Academy graduate opened the scoring after only 90 seconds at the One Call Stadium, cutting inside before curling a left-footed finish into the top corner. Amass, operating at left-back, supplied the assist, while Heaven was named in Darren Moore’s starting line-up for the Elite League fixture.
Celtic loanee Shumaira Mheuka doubled England’s lead before Lacey struck again. The forward reacted quickest after an Amass cross was only partially cleared, taking advantage of the loose ball before beating goalkeeper Matyas Silhavy.
Mheuka added his second shortly before half-time to give the hosts a commanding advantage. Czechia pulled one back through Lukas Moudry after the interval, but England finished strongly as substitute Brooke Nfonkeu-Feuba and Ben Broggio added further goals.
Lacey was withdrawn after 63 minutes, Amass played 80 minutes and Heaven came off at half-time. Manchester United midfielder Jim Thwaites also featured, entering the game for the final 10 minutes.
Moore was impressed by Lacey’s attacking contribution but identified consistency and his work without the ball as areas for continued improvement.
“Not only is his game so exquisite in terms of on the ball, but there’s an end product in terms of his crosses, his deliveries, and his goal scoring,” Moore told reporters.
“What you want him to do is be consistent with it. Off the ball, I want him to do his work early and get him back into position early, and he’s getting better at that.”
The result maintained England’s perfect record in the Men’s Under-20 Elite League, with Moore’s side having one fixture remaining in 2026.
England travel to face Portugal on Monday, 16 November, in their final match of the calendar year. Lacey’s two-goal display will strengthen his case for further involvement as the Young Lions continue their development programme.
The six-goal return also gave Moore an opportunity to assess several players ahead of the next international window.
