Chief executive Ivan Gazidis added: "It's important to acknowledge that the most important thing for this football club, the most important thing for our fans, and
the most important thing for the board and the people that work at the club is how we do on the pitch.
"We have a healthy cash balance of £115million for the half year.
"
But it's important to understand that not all that money's available to invest in transfers.
Gazidis said:
"We can't gear our entire financial model around that — that expectation — because that would place the club in jeopardy if we didn't qualify.
"So we've always got to keep something in reserve in case things don't go our way."
Finishing outside the top four would make Arsenal a less attractive club to current and potential players.
Gazidis said: "There are very few clubs in the world that you would go to ahead of Arsenal in terms of consistently being there.
"I don't see that adversely impacting on our ability to attract players or retain the top players that we have."
