"There are things I have not yet resolved," Bielsa told reporters on the eve of Wednesday's crucial Group F match. "I will announce the team tomorrow."

Argentina will be eliminated in the first round if it fails to beat Sweden, which is top of the group. England needs one point to qualify against Nigeria, which is already out. Argentina has not failed to qualify for the second round since 1962.

"This is my most important match as manager," Bielsa said, but predicted that Argentina would get the necessary three points.

He nevertheless acknowledged he would feel "great sadness" if Argentina is knocked out.

Bielsa said Argentina had "got over" the pain of losing to archrival England.

But the normally placid coach got clearly irritated when asked repeatedly about last Friday's 1-0 defeat.

He accused England of killing the game by defending en masse after scoring a 44th minute penalty.

"We assume the responsibility for having lost," he said. "But people also have to acknowledge that Argentina played with a certain grandeur."

"We could also play like they did, staying back and playing long balls to the attack. But we choose not to.

"We deserved to win, but we didn't. That's football."

When asked whether his decision not to announce his lineup was a sign that he was going to make changes, he snapped: "Interpret it as you like."

There has been speculation that Valencia's Pablo Aimar will replace Juan Sebastian Veron in midfield. Veron would either drop deeper, or be a substitute.

Bielsa would not be drawn on the subject. He praised Aimar, who replaced Veron at half time against England, for his drive which at times threatened an equalizer. But he also said Veron had played well at the start of the game.

Defender Robert Ayala, who would have been team captain, is still ruled out with a thigh injury sustained in the warmup before Argentina's opening 1-0 win over Nigeria.

Asked how the team would try and curb the threat of Swedish striker Henrik Larsson, he simply said: "I have faith in the ability of our defenders."

Bielsa expects a similar game to the one against England, and tried to take some pressure off his players by emphasizing the quality of Group F, known as "the Group of Death."

"It's not a strange situation for us to be in. We always thought we might have to get a win in our last group match."
