Lars Lagerback remains optimistic his attacking talisman Zlatan Ibrahimovic will be fit for Sweden's highly-anticipated second-round clash with Germany in Munich.

The Juventus frontman returned to training on Wednesday after picking up a groin injury during the warm-up for the Paraguay game on June 15.

He sat out the 2-2 draw against England but will be available for selection when Sweden and the hosts open the knockout stages on Saturday.

"Zlatan's last training session went without problems so it looks very positive," Lagerback said. "It is quite possible that he can play."

Lagerback feels his squad is blessed to have all 23 players available.

"Normally you have one or two injuries when you come to the fourth game but we have been really lucky," he added. "Zlatan's injury is the only one we have had thus far so I am happy about that."

The Scandinavians are oozing confidence following their outstanding performance in the 2-2 draw against England when they had Sven-Goran Eriksson's men in trouble for large periods of the second half.

But they enter the first knockout match of the tournament as clear underdogs as high-flying Germany will again count on the boisterous support of a sell-out crowd of 66,000 fans.

Lagerback does not expect the atmosphere to intimidate Brazilian referee Carlos Simon, though.

"Of course I hope our Brazilian friend who will referee the game will have the mental strength to give us a fair game but I expect no less," he said.

"It always helps (the home nation) to have a crowd behind you that is backing you. We felt that support in the first two matches, especially in Berlin against Paraguay. It helped us win the game."

Sweden reached the second round at the 2002 World Cup in South Korea and Japan before stumbling to a 2-1 extra-time loss to unheralded Senegal.

Saturday's match in Munich is far more special, according to the 58-year-old.

"In a way this is the bigger match because we have more support than we had in South Korea and Japan. It will be very special," said Lagerback.

"There is more tension around the game when you play the host nation or a big nation like Germany. We are looking forward to it."

Germany goalkeeper Jens Lehmann revealed he was looking forward to going face-to-face with his good friend and Arsenal team-mate Freddie Ljungberg, who has been consulted by Lagerback regarding any potential weaknesses in the German number one.

"I asked Freddie because he knows Lehmann well but there was not much to say - we all know he is a good keeper with no weaknesses," said Lagerback.

"We are well prepared," he added. "It will be a big match."
