With the tie poised at 2-2, Arteta knows they must play to win and put in a great display.
He stated pre-game: A performance that puts us in the Champions League semi-final.
All the preparation have been to achieve that, and earn it. We have been ready for 10 months and everything we did last season to start that journey in the Champions League after so many years, and tomorrow we have an unbelievable opportunity to make it happen."
He then added on whether he will instruct his players to limit emotion: Emotion is needed in football, it's about tweaking it and touching the right buttons at the right time for the team to always be stable, and be hyped when it has to be hyped.
I think we did that really well in London because after scoring the first goal in the game, we had a big chance to score the second one, and then in 5-10 minutes they are ahead and were in control.
We were mature not to throw everything away in that moment, found our rhythm and our moment to score a really good goal, and the reaction of the team was straight away to score the third one."
