Arsenal boss Arsene Wenger insists his team will go all-out for the win in the Champions League quarter-final second leg against Chelsea.
The Gunners can book their place in the semi-finals with a goalless draw after holding Chelsea 1-1 at Stamford Bridge.
But Wenger said: "Our main aim will be to win the game at Highbury and we
know we can do that.
"We have a good opportunity now and we really want to do it - to go for a 0-0
is a dangerous game."
And Wenger warned Arsenal were now in command after Robert Pires cancelled out an earlier Eidur Gudjohnsen strike.
"We have a psychological edge because, when you are 1-0 up and the other team gets it back to 1-1, it is a big blow," said Wenger.
"I expected Chelsea to be cautious, they defended well and you could see it was a European game because they did not want to concede a goal.
"When they scored there was a 10-minute spell in which we needed to show character and patience, and to come back from 1-0 down is a good result for us."
