Arsene Wenger says the club will not rush into the transfer market following Sunday's shock 2-0 defeat to West Ham at the Emirates.
Arsenal, who were tipped as title favourites, suffered an early slip in their season opener over the weekend, with new goalkeeper Petr Cech looking suspect for both Cheikhou Kouyate and Mauro Zarate's goals.
The Gunners have been heavily linked with a move for Real Madrid striker Karim Benzema, while they are also reportedly interested in bringing Chelsea goalkeeping coach Christophe Lollichon to the club.
However, Wenger insists there will not be any knee-jerk reactions to the loss and that Arsenal will only make a signing if someone of 'exceptional' quality becomes available.
"I would like to think that we are responsible to buy the players and the coaches, not the media," he told reporters.
"When you're a pro footballer, you have to face your responsibilities and not always look at something else.
"We have to look at ourselves and think we were not good enough [against West Ham] and not to think that these kinds of things are solutions for us.
"Again, I can only repeat what I already said. If an exceptional solution turns up, we'll do it. But after a defeat like that, it's important not always to think we take a solution from outside."
