Arsenal will go to the pitch on Tuesday night in the Champions League quarter-finals against Real Madrid.
The Gunners have reached the race only twice in the past 15 years and hosted the Madrid serial winners, which have won the European Cup 15 times in their history.
Arsenal, like other parties this season, have been beaten with injuries and Arteta will have to be a club without midfielder Gabriel Magalha, along with defender Ricardo Calafio, who has been ruled out of the knees with a knee injury.
“There’s something we can’t control,” Arteta said. “What they are preparing for, what they can do is, we must focus on it and we have to understand our strengths and weaknesses and the direction we want to play in the game.
“Obviously, the team’s purpose is very clear, we want to get it tomorrow and we will go to that.
Arsenal manager Martin Odigard, Gabriel Martenelli, Thomas Part, Yurin Timber and Bukayo Sacca have rested.
“At 8 pm tomorrow night, 11 players and 60,000 people, (I) are really very convinced that we are ready to win and beat them. – That’s the thought I want.
“It’s the team that we were the last quarter of the season, with all the ups and downs and things we had to deal with.
