The Dane has admitted that the tournament favourites were the best side in Group B but insists that the Three Lions play against players of that calibre regularly for their clubs
The Denmark captain led his country out in their 2-1 defeat at the hands of Joachim Low's team on Sunday, a result which eliminated Morten Olsen's side from the competition.
Germany were ran close by the Danes, however, needing a late Lars Bender goal to seal victory after Michael Krohn-Dehli had cancelled out Lukas Podolski's opener.
England will face die Mannschaft if the two countries come through their respective quarter-final matches against Italy and Greece respectively.
Germany would be heavy favourites for such a game, having thrashed the Three Lions 4-1 at the 2010 World Cup, but Agger believes the England players play against opposition of such quality regularly in the Premier League.
"Germany were the best team in our group when they had the ball, but we felt we had a chance against their defence," Agger told The Sun.
"Their front three don't stay in one position, they're constantly changing sides and running into new positions. But I play against strikers of that quality every week in the Premier League and so do the England players."
Germany are currently on a 13-match winning streak in competitive fixtures and will look to continue that run against Fernando Santos' team on Friday.
