The Gunners were disappointing on Sunday in their 1-0 home defeat to Leicester City, which was their second consecutive loss in the Premier League after they were beaten by Manchester City last weekend.
Keown said on Stadium Astro: "They keep changing from one system to another and they did this with Emery.
"That's what I would like to see now, the same pictures, the same triangles, the same movements, the same partnerships, the same relationships."
"If you keep changing it, you don't find a rhythm, and that's something that I found in a very successful team.
"It was like putting an old pair of slippers on for a game. Everything was there. You'd fire it into midfield to Patrick Vieira, into Dennis Bergkamp, [Thierry] Henry into the channel; it was three passes.
"These players now are getting the ball now and it's jamming a little bit, so I think keep it simple and start building from this team. If this is the way he wants to play, keep with it, and try to put the people in it and get the messages right and work on it.
"It was very static, the front three never really moved from positions, they didn't make themselves available."
