Arsenal captain Cesc Fabregas has assured fans the team will perform on Tuesday by overcoming Manchester United to reach the Champions League final. At Old Trafford, the United had plenty of investment on display in their first XI, while Sir Alex Ferguson decided to leave record £30million striker Dimitar Berbatov on the bench.Arsenal's young side cost a fraction of that outlay.

"It does not mean that because one player cost £20m, he is better than one that cost £2m," said the 22 year old.

"It has been shown with the likes of Patrick (Vieira), Dennis Bergkamp, Robert Pires, Thierry Henry - they are the best players in the world, have won World Cups, European Championships and some players who have cost £20m or £30m, they have not won anything."

Fabregas declared: "We know what we can do, we know we are good and we just have to be positive and believe we can do it.

"We know we can be really strong if we play as a team and individual stuff will come during the game. The most important thing is that the team is united and we are."

"At home we know we are very strong and will have our fans behind us," the Arsenal captain said.

"When you play at home it is completely different for any team in the world.

"You are playing behind your fans, you know the stadium, the pitch, the grass is better.

"You know where you have to play the ball and when you do not have to play it.

"As a team, if we are strong, compact, and put pressure on them I am sure we have a great chance of going through."

Fabregas added: "We just have to play our game, be confident we can do it because I know we can do it.

"Let's focus on our game, be positive and go for it."
