Bolton manager Gary Megson believes the form of England's teams in the Champions League has proved the country has the strongest domestic championship in the world.
Holders Manchester United, 2005 winners Liverpool, last year's runners-up Chelsea and 2006 finalists Arsenal all made it through to the quarter-finals.
"It should temper some of the expectations of a lot of Premier League teams," said Megson of the big four's dominance of Europe. "The Premier League is the strongest league by a street and when Liverpool play as they did the other day that is how we are playing against them all the time."
He added: "When you look at what we are playing against week in, week out, Real Madrid (against Liverpool) can't handle it, Inter Milan (against United) can't handle it.
"If Madrid can't handle it that shows how difficult it is for the rest of us."
Arsenal, Chelsea, Liverpool and Manchester United will be in next week's draw alongside Barcelona, Villarreal, Bayern Munich and Porto.
Megson said the vast wealth of the Barclays Premier League had made such domination possible.
"It's money, pure and simple. If the money wasn't here the foreign players would be playing in their own countries," he added.
"It is a big draw as it is in every walk of life and we have got the wealthiest league in the world, so it attracts the best players in the world.
"We have to realise how impressive the Premier League is to the rest of the world."
