One of the pre-tournament favourites, Germany were outplayed by the Croatians last Thursday as they slipped to a 2-1 loss in Group B.

Joachim Low's men travelled to Vienna on Sunday ahead of their decisive clash with Austria on Monday.

A draw with the co-hosts would be enough for Germany to qualify for the quarter-finals, but Ballack insists they are looking for more following their recent disappointment.

"Everybody is a bit tense after this loss, which is normal," said the Chelsea midfielder.

"If it were any different, then there would be no reaction. But we go into the game with this tension and the pressure to win, which brings a few more percentage points out of you.

"We have this pressure but we have shown in past that we can deal with it.

"I hope that we show a reaction on Monday and win the game.

Ballack also admits the atmosphere inside the Germany training camp has altered over the last few days.

Rather than the relaxed feel which surrounded the squad on their arrival in southern Switzerland almost a fortnight ago, the seriousness of the task in hand has come to the fore.

"Football is not always harmonious," admitted Ballack. "The voices in the team have got louder and people have been

giving their opinion, but it is all constructive.

"What is decisive is that it is positive and aimed at the success of the side, but every player knows it and the important thing is that a reaction comes of it."

"We have lost a game, but still have a chance. We are still in the tournament and the situation has not changed.

"We have got to win every game from now on in."

While Ballack admits he would have been happier heading into their final group game having already secured a place in the last eight, he knows what to expect in Vienna on Monday.

The crowd will be largely Austrian and hostile, and the stakes for the hosts are even higher as they look to cause an upset against their more illustrious neighbours.

"I think we are favourites and Austria know they have nothing to lose, given the way they have been talking," Ballack continued.

"It will be tough with a full stadium and the home fans getting behind them, but we knew this would be the case before the tournament began.

"Although it would have been nice to be sitting here already qualified, that is not the case and we need to put our foot down.

"But with the right attitude and the performances of recent months, we have nothing to fear."

Coach Low has promised to make changes to the side which lost to Croatia, although it is unclear how the Germany team will look on Monday.

The 4-4-2 system will probably be maintained, but the personnel are expected to be different. Marcel Jansen is definitely out injured while Bastian Schweinsteiger is suspended.

Lukas Podolski may be moved up front with Kevin Kuranyi or Oliver Neuville given a chance alongside him, leaving two spaces on either wing to occupy assuming Clemens Fritz reverts to full-back as he did in the latter stages of the Croatia game.

Those decisions will be made after the final training session in the Austrian capital on Sunday evening, and Ballack insists all of the 23 squad members can perform better than they did on Thursday.

"All the players who were on the pitch against Croatia can improve and we know that," he said.

"We will have to wait and see what the team looks like and I think every player will be motivated, whoever plays tomorrow.

"I remain 100% convinced we will win, and it is less important who is on the pitch than how we go about the game."

Low's assistant coach Hans-Dieter Flick also admitted "we have to change something", although he is confident he will not witness a repeat of the Croatia match.

"You have got to look at the quality in the team and I am absolutely sure that if we can show that, then there will be only one winner, and that is us," Flick said.

"There is definitely no plan B for us."
