Arsenal hero Ray Parlour has urged management to deal in Bukayo Saka and Gabriel Martinelli.
Ashley Cole, Cesc Fabregas, Samir Nasri and Robin van Persie were all sold as a result of contract standoffs that meant Arsenal were forced to get rid before they could walk away for nothing.
"We've seen it happen so many times at Arsenal where people have gone on free transfers," Parlour told talkSPORT.
"Back in the day [Robin] van Persie – free transfer more or less. We had to sell him with a year left [on his contract].
"[Samir] Nasri was in the same situation. So now you've got to highlight who you want to keep, who's your players going forward."
Parlour said key to Arsenal's future was ensuring that Saka and Martinelli are tied down to avoid the prying eyes of potential suitors.
"I'm sure there'll be so much interest for Saka. All the big big boys will come in and try to sign him," Parlour added.
"So now sit down with him, get him on a good contract. Martinelli's in the same boat – they've got to try to nail him down as well.
"[Emile] Smith Rowe has just signed a new contract, I know he's injured at the moment but you've got to try and get these youngsters to sign up and believe that in two or three years time, this club is going somewhere."
