England front three won't be great until they deliver in big games, according to Raheem Sterling.
The Manchester City star is expected to line up with Harry Kane and Jadon Sancho against Czech Republic on Friday, with Callum Hudson-Odoi, Callum Wilson and Marcus Rashford as alternative options.
"I think that there are a lot of great front threes in the world," he said.
"I think with the players you mention, they're all players that are still getting better, still learning, but at the same time are producing as well, so it's an exciting front three, but you know, we've got to do it in big games, big tournaments.
"That's when we'll be judged if we're a great front three or not."
