Harry Redknapp was the English former football manager and player.
The 73 year-old has urged the Gunners to sign Aston Villa star Jack Grealish.
Speaking about Arsenal on his own podcast called The Harry Redknapp Show, he said: “I think they have to spend.
“They are way off it, at the moment. They need to bring a bit of quality. Arsenal is a massive football club… take a Grealish.
“He needs to play at the bigger club like Arsenal.”
It has been widely reported that Grealish will cost £100 million to sign next summer.
Arsenal have reportedly made contact with Emiliano Buendia’s agent.
Transfer guru Fabrizio Romano told Arsenal Fan TV: “He’s one of the options.
“There has been contact with his agents in the last few weeks, Arsenal making some enquiries with many agents as they look for a quality midfielder.
“They are interested in Buendia but it’s not sure he will be the perfect player.”
Mikel Arteta is believed to be very interested to sign the Norwich playmaker this month.
