Arsenal manager Arsene Wenger insists that two heavy home defeats in the space of a week will not persuade him to panic buy in the summer.
The Gunners - who were dumped out of the UEFA Champions League semi-finals by Manchester United on Tuesday following a 3-1 second-leg defeat - were comprehensively beaten 4-1 by London rivals Chelsea at Emirates Stadium on Sunday.
Chelsea's victory over their capital rivals guaranteed the Blues a finish in the top three of the Premier League, leaving Arsenal with a best possible finish of fourth place.
Question marks have developed regarding Wenger's side after conceding seven goals in a week, but the Frenchman is not overly concerned and insists his close-season transfer plans will be conducted in a thoughtful manner.
Wenger said: "You would not like to come out and say we will buy four defenders.
"It is more a question of balance in the team rather than individuals."
He added: "At the moment, I don't know what funds will be available. I will be told by the club.
"We have to continue to improve, but the areas where it is right. It is not necessarily about quantity of money."
The Arsenal boss is also adamant that his side, who wasted a
host of chances against Chelsea, did not deserve to lose to their capital rivals.
"We have to take some distance, because it was not a 4-1 game today," he said.
"Going forwards we were very interesting and created plenty of chances, and should have been 2-0 up, but were caught.
"We missed seven or eight clear chances and had every mistake punished by a team of quality."
Wenger added: "Our chances to finish third are over, but this result will not have any other influence other than that.
"We conceded three against Manchester United and four today, so we have to improve the way we defend.
"In the games that mattered in the last three or four weeks, we could not win. That is what we have to analyse."
