Arsenal manager Unai Emery said he is happy to be patient in the transfer market and will wait for the right player to become available.
The Gunners head coach was speaking after watching his side make it two wins from two in the International Champions Cup with a 3-0 victory over Fiorentina in Charlotte.
"Really I am with patience because we want to choose the best solution," Emery said. "Some players are very expensive and we are waiting for this possibility.
"We don't want now to go to the second line of players.
"We are waiting. We have very good players. We have very good young players.
"We are aware also that we need to improve some players in this squad. I want to sign one, two, three or four players only if we can be sure they are coming to improve our team."
Arsenal have been linked with William Saliba in the British press, in a deal that would see the defender return to current club Saint-Etienne in France on loan as part of the deal.
Emery, however, said there were a number of possibilities floating around and he was in constant contact with sporting director Edu and head of football Raul Sanllehi, while they also spoke with the club's owners the Kroenke family.
"There are a lot of names. The club is working, Edu is very close to me and Raul," Emery said. "We speak every day."
After impressing in a starting role in Saturday's win, 17-year-old Bukayo Saka said he is ready to prove that the Gunners don't need to look externally for new first-team talent.
"The players coming up from the academy are so special," Saka said. "The next generation of us can be in this Arsenal team and take on the world.
"The boss is doing a good job of managing all of us, helping us to progress every day and to learn.
"I just have to keep pushing. Showing the boss what I can do and when the time comes I am ready to play. When I get the chance then I can take it."
Saka also hailed the influence of new Arsenal assistant coach Freddie Ljungberg, who has been promoted from the Under-23s role to work alongside Emery, bringing a wide knowledge of his former charges.
"From the Under-15s I worked with him," Saka added. "It has been a long journey but I feel like we both deserve it.
"Freddie helps Unai know who we are, tells him our strengths and weaknesses and comes to us individually and tells us what we need to do from Unai.
"Unai does not have to speak to us directly, Freddie comes to us and tells us what we need to do. It makes the transition from the academy to the first team much smoother."
