Mikel Arteta insisted that Arsenal is ready to do 'something special' in Paris next Wednesday to keep their dream alive from achieving a First Champions League final since 2006.
The Gunners were surpassed and hit their hope after Paris Saint-Germain last night hit four minutes at four minutes by Ousmane Dembele in the semi-final first leg.
Mikel Merino had excluded a goal for offside early in the second half, but the North -London club was lucky not to experience a broader backlog with Goncalo Ramos who touched the bar.
It gives the French visitors a 1-0 advantage that goes in the Parc des Princes's second stage next Wednesday.
Arteta said: 'We are during the break and my message is exactly the same (as it) against Real Madrid (first leg) at home with 3-0. We have to go to Paris and win the game. We are more than able to do it.
'I saw two very good teams, but the margins are so small. They had efficiency for the goal. Their keeper (Gianluigi Donnarumma) also made a difference to see the result we have seen tonight.
'I don't know the percentage, but we have many opportunities to be in that final. While I repeat myself, you have to do something special in the competition to have the right to be in the final. And the time to do this will be in Paris. '
Arsenal never won the European Cup and last reached the final in 2006. Now Arteta's opportunities to reach the showpiece of this season in Munich on 31 May will require a large comeback.
But David Raya was also convinced that his side could destroy the shortage next Wednesday.
Raya said: 'I didn't see it -accessible goal. I think we needed that lift. But we have shown the last 70 minutes that we can win against each team. We are going to Paris next week to win the game.
'We will try to approach the game in the same way. I thought we played very, very well. They also had their chances, but that is football.
“It's just the peace. We have created opportunities and we are still in it. '
PSG abandoned Manchester City in the group stage before he defeated Liverpool on penalties in the last 16 and then eliminated Aston Villa in the quarterfinals. The side of Luis Enrique is now on the edge of another Premier League head skin, but the Spaniard is still on their guard.
Enrique said: 'It is mission finished for this evening. But our goal is to win the second stage at home.
'With Arsenal we cannot abandon our guard or be complacent because they can score quickly and we are back to. There is nothing in the bag. We have to win when we get home, because Arsenal now has nothing to lose. '
