However, Arteta does not want his team to feel sorry for themselves, but to learn from the defeat at Bayern.
Post-game, he said: We haven't been in the Champions League for seven years, we haven't been in this position for 14 years, but our intention is to fast-forward everything and in our first season, be ready to play in the semi-finals and we were very close.
Unfortunately, we haven't managed to do it, so we have to learn from it, me first, and earn the right to be in the same position next season.
I'm obviously very sad. The dressing room is very disappointed. We had a lot of hope and invested a lot to go through, but the margins in this competition are super small, and we lacked to make the difference in those moments.
We had our moments again. I think the team played with a lot of personality, but we lacked that magic moment at some stage or to force a mistake, because that happens as well to go through in the tie. We have to congratulate Bayern; they have done it, and they are through."
