The north London side have been linked with a host of big names over the last few weeks but they have so far only signed Brazilian teenager Gabriel Martinelli.
Arsenal are looking to strengthen their squad after they finished in fifth place in the Premier League table and without a trophy last season.
The Gunners do not have the lure of Champions League football to attract potential new signings after they lost the Europa League final to Chelsea FC last term.
However, Emery has now revealed that the Gunners are working hard on sealing some important deals before the English transfer window closes at the start of August.
Speaking in an interview quoted by the Daily Mirror, Emery said: The club is working. We are speaking every day with the club and Edu.
“I prefer to work with patience and calm and take the best decision.
“We have very good players, very young good players. We need someone to help us. The club is working on that.
“We prefer to take the best decision with patience. If we need to wait more time for this reason I prefer to do that.”
Arsenal have not won the Premier League title since their famous unbeaten triumph in the 2003-04 campaign under Arsene Wenger.
The primary target for the Gunners next season will be to break back into the top four and secure a return to the Champions League.
Emery was brought in as Wenger’s successor in May 2018 after the Frenchman called time on his decorated spell at the north London club.
