Sweden top qualifying Group Eight but are under pressure from unbeaten Bulgaria - who the face in a key match on Saturday - and Croatia, who handed the Swedes their only defeat so far.
"We have Bulgaria away in Sofia," said Erik. "It is a tough one, but I have great faith in the fact we will do well.
"We are top of the table but the other teams have a game in hand or two. Croatia is probably our main rival, while Bulgaria have a good young team again now with Hristo Stoichkov as coach.
"There is also Hungary, who are an interesting team as well. It is not the toughest group, but one where people expect you to win every game even though they are still difficult.
"We have a strong side and only Henrik Larsson is injured. Okay, he is maybe our best player, but we have some good substitutes and alternatives to fill the place."
It means Sweden's main attacking force will be Juventus striker, Zlatan Ibrahimovic, Mido's former team mate at Ajax.
Erik is expecting big things. "He needs to bring all his Juventus quality to Sofia," he added. "Marcus Allback, my big friend, might partner him attack or they could call a new one - Marcus Rosenberg from Malmo. He is a really strong talent who has played really, really well in the last couple of months after having a great season with Halmstad last time."
Having performed so well in Euro 2004, Erik Edman knows full well the importance of Sweden making the 2006 World Cup Finals.
