Former Arsenal vice-chairman David Dein thinks Unai Emery should be aiming for a top-two finish this season.
The Gunners have finished second just once in 14 seasons and have not finished in the top-four for the past three seasons.
But Dein, who served the club from 1983 to 2007, believes top-two is achievable this season.
"I think it's a work in progress. We have to patient," Dein told Sky Sports.
"It's not easy today as everyone expects instant success, and you can see what has happened to other club around us.
"Everyone thinks it is so easy, you turn the tap on and you get hot water, but it's not quite as easy as that.
"[but] I think we set a certain standard and we expect them to be up at the top challenging for first or second place."
