Hamren was asked about possible England concerns that the Swedes, eliminated from the tournament, would field a weakened side in their last Group D match against France.
"Make sure you win yourselves," he advised England. "That's the best thing. They can concentrate on themselves and we'll concentrate on our own game. Our ambition is to get a good performance and a good result."
"We can go out and perform with everything to win and nothing to lose," he told a news conference.
"It's the last game, and if we win tomorrow we don't have three points in the World Cup but we have a lot of feelings and self-confidence when we start the World Cup qualification," he said.
"It's a big tournament, we've waited and prepared for it, so for us it's about finishing the job and starting to prepare for the World Cup qualifiers.
"The support we've had from Swedish supporters has been fantastic and there'll surely be lots there again tomorrow, it's a great source of motivation. We're here to play, even if we can't go through."
"I have spoken to him about it and he has said that this is his last tournament, but that doesn't mean he won't play a part in the qualifiers," Hamren said. We'll see what happens."
