Barcelona midfielder Andres Iniesta is confident his side can progress past Manchester United and reach the Champions League final, despite their poor recent form.
Barca's goalless stalemate with local rivals Espanyol on Saturday was the team's third successive league draw, while in their last 13 competitive matches Frank Rijkaard's men have recorded only four victories.
However, Iniesta remains in buoyant mood ahead of Wednesday's Champions League semi-final first leg against United at the Nou Camp, saying: "It's very important for us to get to the final, and we have 180 minutes ahead of us to do so.
"We can do it, but we need to change our mindset for the two legs, and we can't afford to give anything away."
Barca have won eight and drawn two of their 10 Champions League matches.
"The Champions League is another story," added the Spain international. "A good example is that after a terrible game in Seville against Betis, we were able to beat Schalke in Germany."
Iniesta knows, though, that it will not be easy against the Premier League champions, especially with their attacking triumvirate Cristiano Ronaldo, Wayne Rooney and Carlos Tevez in good form.
"They have some great players who can change a game at any moment," said Iniesta. "I'm worried about them as a team, but not about any player in particular. They are a great side, and we'll have to be focused, but I think they will also be worried about us."
Barca look set to have playmaker Lionel Messi fit and available after recently returning to action following over a month out with a hamstring injury, and although he is likely to provide United with some major headaches, Tevez is glad his countryman will be involved.
"I hope that he plays. If we beat them with Messi they will have no excuses," he said. "He is from another planet. He is very quick out of the blocks, he is a fantastic player."
