Liam Brady expects Arsenal to do "a lot of business" this summer, and also believes Samir Nasri will stay at the club.
Gunners manager Arsene Wenger has hinted at a fair amount of activity on his behalf in the transfer window.
Wenger is looking to bolster his side after the team's search for a first piece of silverware since 2005 was extended.
Brady, head of youth development at Arsenal, told talkSPORT: "I think Arsenal will spend this year.
"There will be a lot of business done this year and I think we will be spending a bit more money than we have done in past seasons."
But Brady did warn of the competition Arsenal face in bringing quality signings to Emirates Stadium.
"Where are the players to go around everybody? It is not only the clubs in England, but also all the big European clubs are in the transfer market," he said.
Brady went on to express his optimism that Nasri will remain an Arsenal player, despite the Frenchman's future being uncertain after entering the final year of his contract.
"We all rate Nasri," Brady said.
"I believe they had extensive contractual talks but not reached a conclusion, but sometimes it takes time.
"I am optimistic he will be playing with Arsenal next year."
