The Norway international believes Roy Hodgson's players are struggling after a tough Premier League season.
England face Norway's Scandinavian neighbours in Kiev on June 15.
And Hangeland, 31, said: "Sweden have a good chance.
"It's a good England team but they look a little worn after a long season.
"It's not good preparation for the Euros to play such a tough season.
"Even if it was a friendly, you could see that the English players need a break."
