The Spaniard admits that securing a place in the Europa League final is crucial for the club's short-term health, as it could determine what they're able to do in the transfer market over the summer.
He said: "I'm really focused on what we have to do now: finish the season as strongly as possible and try to get into that final, which is going to be key for us.
"Where we want to get to will depend on a lot of things; how we end the season, where we end up, what ability and prospects we'll have for next season. Everything is a reflection of what happens now."
Arteta admitted that this summer could be the most important in Arsenal's recent history.
He told Sky Sports: "[Yes, it could be] because a lot of things have happened in the last few transfer windows. There are a lot of players in various situations. It's crucial.
"We want to go to the next level and there are a lot of things we need to do to get there."
Despite winning the FA Cup last season, Arteta admits the Gunners are still a long way from where they want to be.
He said: "I will say there's still a long long way to go to get to where we have to get. [The timeframe] will depend on what we do.
"We've shown in big moments against big teams that we can beat anybody but the reality is that we haven't showed that consistency every three days.
"We've faced many challenges, some we didn't expect, some of them completely unprecedented in the outside world and at this football club. To manage all that is pretty difficult. It's created unsustainability and instability.
"People will judge what we do today but lots of elements are contributing. I haven't had a normal season yet. Without a proper pre-season, we had some instability, and [we need] our fans back in the stadium ... I cannot wait for that."
