Arsenal technical director Edu has defended the Gunners' transfer policy, with the club bottom of the Premier League after three successive defeats.
Arsenal spent in excess of £150m on new signings this summer - more than any other Premier League club.
But Mikel Arteta's side have started the league season with defeats by Brentford, Chelsea and Manchester City.
"I think we have to see the wider context than just the money around it," Edu told Sky Sports.
"We signed six players who are under 23, which means a lot in terms of our planning.
"We started planning this squad a year ago in terms of consolidating the team and trying to get a better foundation. We have to balance the squad better."
