Arsenal boss Arsene Wenger admits he must buy experience after defeat to Liverpool.
Wenger concedes they looked naive at times on Saturday.
"We were a bit young," said the Arsenal boss. "We looked a bit naive in some situations, as well. But we have shown a great spirit and we were really unlucky. I don't feel we deserved to lose the game.
"We will buy. People feel I'm stubborn. I'm not. I just want to do the best for the team and buy the right players.
"If I have shown one thing in the last 15 years, it's that I've brought good players here.
"We will bring as well experienced players. People say "buy" but it's to buy the right player which is difficult. We have bought players - Gervinho, Chamberlain, Jenkinson, Miyaichi - and you will see during the season they are top quality."
