Eriksson insisted he was confident that, even after the tumultuous week he and his players have endured, they remain focused on the game.
He said: "Even if a lot of things have happened, the practice session we had was extremely good and the players have worked very hard."
Eriksson said the match "is a very big game" but that it was not the most important in his time as England coach. "That must be Argentina because it was in the World Cup," he said. "And whoever lost that match would go home."
Eriksson added that the most important factor for his team tomorrow would be how they handled the pressure.
"Even if we don't have any fans here we will appreciate the atmosphere. We will try to play as we normally do, to be organised. The most important thing in a game like this is to keep a head as cool as possible for every moment of the 90 minutes. If we do that we have a big chance of making a good result."
Eriksson admitted, however, that the pressure would be on him if his team lost tomorrow.
When asked by a Turkish journalist if a defeat would mean the English media would "hang him", he replied: "I am quite sure. But what is new? Every time you lose in this job you are slaughtered, but you have to accept that."
He said that, contrary to reports, there were no rifts in the England camp.
"It has been a different week," he said. "But the players are fully focused. If you had seen the excellent practice sessions we had, you would not know anything else has happened.
"I hope they are concentrating tomorrow evening and I'm sure they will. They are very professional. Even if it is a young team there is a lot of experience. It's a big game tomorrow and it means a lot to get a result. I think you will see a very good England team."
Eriksson, asked how he approaches such matches in terms of team talks, replied: " Normally when you play big games you speak less because they [the players] are very focused.
"If you play against lesser teams there can be a danger of complacency - but tomorrow, no one will underestimate Turkey."
