Arsenal chief Ivan Gazidis admits their lack of silverware isn't good enough.
Gazidis wants to build on last season's FA Cup triumph.
He told Arsenal TV: "I'm not satisfied. You need that constant pressure, that constant drive, striving to improve, get better and put everything out on the table - you need that. It's been frustrating for the fans. I know it's been enormously frustrating for Arsène and for me.
"It has been incredibly frustrating not being able to be where we want to be these last few years, so winning the FA Cup was a fantastic moment. In my life, that's one of my greatest moments, to feel that and to go on the open-top bus tour. Not for me, but to see the fans and what it meant to them - that was an incredible day for me and all the staff and players that were a part of it.
"I don't come out of that feeling satisfied like we've achieved what we need to achieve."
