Rice silenced the boos that greeted his every touch with a thumping finish into the top corner on 11 minutes.
The Arsenal midfielder then turned provider for Grealish to fire in his first international goal since the 2022 World Cup.
"I'm pleased with it but not surprised. I think they've both been in football long enough now to understand and respect that it was going to be a little bit hostile at times, but in the right way," said Carsley. "Obviously, it's great for them two that they've scored the goals but more importantly that the team has won and they've kept a clean sheet."
