England midfielder Trent Alexander-Arnold says the Three Lions know they need to improve after narrowly beating Serbia in their opening Euro 2024 match.
Jude Bellingham scored the only goal as England won 1-0 in their tense Group C opener.
Serbia pushed forward after the break with Jordan Pickford needing to produce a couple of saves to preserve victory.
Alexander-Arnold conceded that his side "could have performed better" but said it was "very important" to start the tournament with a win.
"In tournament football that's the only thing that matters," he said. "Keep up the momentum, don't get ahead of ourselves.
