England manager Gareth Southgate said the team's fans can try to intimidate Italy but should remain respectful and not boo their national anthem in today's European Championship final at Wembley (live on RTÉ2 and RTÉ Player).
A section of England fans booed when Denmark's national anthem was played before their semi-final meeting at the same venue in London.
Jeers were also heard when the German anthem was played at Wembley when England beat Joachim Low's side in the round of 16.
On Saturday, European soccer's governing body UEFA fined England's Football Association €30,000 for fan behaviour that included the booing, setting off fireworks and a laser pointer being shone at Denmark goalkeeper Kasper Schmeichel.
"It's important that our fans always respect the opposition and we know that in fact when we play abroad and fans boo our anthem it probably inspires us even more, so I don't think it will help the team," Southgate said.
"I think we can intimidate the team with the booing during the game, but it's different for the anthem. I think we should be respectful."
Former England international Gary Lineker made a similar request to the country's fans last week.
"If you're lucky enough to get a ticket for the final, please, please don't boo the Italian anthem," Lineker tweeted on Thursday. "A/ It's an absolute belter and worth listening to. B/ It's bloody rude, disrespectful and utterly classless."
England have not won a major tournament since their solitary success at the 1966 World Cup and the country is gripped with anticipation of ending that wait today.
In a letter to the team wishing them good luck, Queen Elizabeth recalled presenting the Jules Rimet trophy to Bobby Moore almost six decades ago.
She said: "Fifty-five years ago I was fortunate to present the World Cup to Bobby Moore and saw what it meant to the players, management and support staff to reach and win the final of a major international football tournament.
"I want to send my congratulations and that of my family to you all on reaching the final of the European Championships, and send my good wishes for tomorrow with the hope that history will record not only your success but also the spirit, commitment and pride with which you have conducted yourselves."
Meanwhile, Harry Kane is out to "finish the job" and fire England to glory by maintaining his scoring streak.
The Three Lions captain promised he would peak at the right time amid fierce criticism after he went through the group stage without a goal.
And he has been true to his word as four goals in the last three games have put England one game away from a first piece of silverware since the 1966 World Cup, with a Wembley final against Italy the last hurdle left to overcome.
He grabbed the nerve-settling second goal against Germany, netted a brace against Ukraine and then scored the winner in extra-time in the semi-final against Denmark.
It is the reverse of how things panned out for him three years ago at the 2018 World Cup when he scored six goals before the quarter-final but lost his edge for the big games against Sweden and, crucially, Croatia.
Kane says he learned from that experience and was able to shut out the noise when some critics were calling inexplicably for him to be dropped.
"Don't get me wrong, I'd love to have scored three or four goals in the group stage and got off to a fantastic start and gone from there," he said.
"But it was about the energy. I felt in the World Cup, with such an amazing start, with scoring in the last minute against Tunisia, a lot of energy was used up because of the emotion.
"Panama was the same. We had an amazing game, I scored a hat-trick and there was a lot of talk, a lot of mental energy (spent up).
"Colombia was the same. Not just physically, but maybe mentally I lost a little bit towards the latter stages.
"So going into this one with more experience, it was just about not getting too carried away, whether I score or don't score.
"Obviously we were winning games which was the most important thing, so it was just about staying in the moment, not getting carried away and knowing that as a player and as a team we were on the right track.
"Thankfully it's worked out pretty well and I guess that's all part of the learning curve of playing in major tournaments and gaining that experience. Hopefully I've got enough left to finish the job."
