Leicester and England great Peter Shilton believes the giants of European football will all want to avoid the Foxes in the Champions League quarter-finals.
The East Midlands outfit are the last English team left in the competition after Manchester City were knocked out by Monaco on Wednesday.
Craig Shakespeare's side will discover their next opponents in Friday's draw after they beat Sevilla 3-2 on aggregate following a 2-0 win at the King Power Stadium on Tuesday.
Real Madrid, Barcelona, Atletico Madrid, Juventus, Bayern Munich, Monaco and Borussia Dortmund have been European champions 24 times between them and are all possible opponents for debutants Leicester.
Juventus' Gianluigi Buffon and Madrid boss Zinedine Zidane have already said they do not want to face the Foxes and former goalkeeper Shilton, England's record appearance holder, understands that point of view.
It's what teams will think. They're going to cause problems to anyone they play.
It's not going to be easy but they are through to the quarter-finals and anyone who is there can win it. But you're not going to start shouting from the rooftops and saying they definitely will because there are too many wonderful sides.
I hope they get Real or Barcelona, the fans will want to see that. They have done the country proud.
Obviously it hasn't been a great season up until now, it was the heights of utopia to the depths of despair in three-quarters of a season and everyone was shaking their heads. To get into the quarter-finals is a terrific achievement and anything more would be a dream.
Bacary Sagna admitted Manchester City lacked fight as they were dumped out of the Champions League in Monaco.
City surrendered their 5-3 first-leg advantage as they lost 3-1 at Stade Louis II, exiting the competition at the last-16 stage on away goals.
Manager Pep Guardiola's bold attempts to combat Monaco's dangerous forwards by going with an all-out attacking approach himself backfired as City failed to gain any meaningful first-half possession.
By the interval they were 2-0 down after goals from Kylian Mbappe and Fabinho, and although Leroy Sane put City back in control, a powerful header by Tiemoue Bakayoko settled the tie.
The loss realistically leaves the FA Cup as City's only remaining route to silverware this season, but a quick response is required ahead of a vital Premier League clash against top-four rivals Liverpool on Sunday and Sagna has conceded he expects a big reaction.
It is a massive disappointment. We forgot to play in the first half, we forgot to fight as a team, defend as a team and press as a team. We gave them too much respect and against these kind of players, we put ourselves in danger.
We have to congratulate them, they are through. We are out and we have to recover because on Sunday we have an important game.
I expect a reaction from the team. I expect more desire, to show more passion. We did show passion in the second half but it is not enough. We have to recover because it was quite a difficult game and then we have to think about Liverpool.
We changed the system and I think it worked quite well, we managed to create more chances, but unfortunately we didn't score (enough).
They are probably the most scoring team in Europe at the minute. We knew they had quality players, we knew they had dangerous players.
We conceded six goals over two games. It is never easy to take but we have to, unfortunately.

Marc Albrighton has warned Europe's elite that Leicester will continue to upset the establishment.
The winger scored the Foxes' second in their 2-0 win over Sevilla to send them into the Champions League quarter finals 3-2 on aggregate on Tuesday.
It was just his second goal of the season - having scored Leicester's first ever Champions League strike at Club Brugge in September - after Wes Morgan opened the scoring to put the hosts ahead on away goals.
They lost the first leg 2-1 in Spain but recovered and could now face holders Real Madrid, Barcelona or Bayern Munich in the last eight.
Ahead of Friday's draw, Albrighton insisted the Foxes are not about to stop the shocks now.
I don't think I saw one person say we were capable of going and winning it (against Sevilla). We have defied the odds there, we will go and do it again.
I don't know whether they will fear us or whether teams might want us as it is odd seeing Leicester among those names but Sevilla didn't expect what they got.
They didn't expect us to be so in their face. If other teams come here they will obviously have to be wary of that. I would take anyone, there is not a bad team in there. Anyone would be fantastic.
We will continue to enjoy this and see how far we can go.
You don't enter a competition and aim not to win. We want to go all the way and believe we can. We believed we could win this game and the next step is the quarter-finals.

Yaya Toure believes some critics are waiting for Manchester City to fail as they prepare to go full throttle in Monaco this week.
City seem to have put the inconsistencies of the autumn and early winter behind them by going 11 games unbeaten since a humbling 4-0 loss at Everton in January.
That has put them in good heart for the second leg of their Champions League last-16 tie against the Ligue 1 leaders, into which they will take a 5-3 aggregate lead, on Wednesday.
But midfielder Toure feels the momentum must be maintained to keep the knockers off their backs.
When you're a winner and when you want to achieve important things you have to work hard. Sometimes it's difficult but you have to be positive because we know people are waiting for us to fail. What we have to do is try to keep going, working hard.
We are playing very well at the moment and we have a team that plays mostly attractive games and sometimes the pundits are waiting to analyse.
But, okay, it's part of the game, and in football now. Ten or 20 years ago it wasn't the same but today we just have to do our job.
We are playing well but in the end winning is the most important thing.
Leicester midfielder Danny Drinkwater has backed Craig Shakespeare to stay beyond the summer as the Foxes prepare for their Sevilla showdown.
New boss Shakespeare was named as the club's new manager until the end of the season on Sunday.
He replaced Claudio Ranieri after the Italian was sacked last month, just 24 hours after Leicester's 2-1 Champions League last 16 first leg defeat in Seville.
Shakespeare, who was Ranieri's assistant, takes charge of his first game as a full-time manager in the second leg at the King Power Stadium on Tuesday and insists he has not thought about the job beyond the end of 2016/17.
But Drinkwater wants to see the new manager stay for a long time.
On behalf of all the players I think all of us would like to see him get the job long term.
It's a great appointment. It's a good fit. We haven't got much time to turn things around but there's no better person for the job.
I don't think it's changed an awful lot. He needs to take control more as manager and any changes he's made have been positive for the players.
He's been a pleasure to work with as manager - but he's taken different roles as a coach. He helps us enjoy the football. It's not only for the players and manager but one of the biggest games in the club's history.
