England have been hailed as heroes who should be "so proud" of themselves for their efforts in reaching their first major final in more than half a century.
In a nail-biting final of the Euros, the Three Lions faced an agonising defeat in a penalty shootout at Wembley.
Prince William, who was at the match with the Duchess of Cambridge and their son Prince George, urged the players to "hold your heads high".
In a tweet from the KensingtonRoyal account, signed W, the Duke of Cambridge congratulated the Italian football team on their win.
He wrote: "Heartbreaking. Congratulations @Azzurri on a great victory. @England, you've all come so far, but sadly this time it wasn't our day. You can all hold your heads high, and be so proud of yourselves – I know there's more to come."
Prime Minister Boris Johnson, who was also at the match with his wife Carrie, tweeted: "That was a heartbreaking result to end #Euro2020 but Gareth Southgate and his @England squad played like heroes.
"They have done the nation proud and deserve great credit."
