The Cottagers have scored more goals than anyone but Manchester United and Chelsea this season, but the boss believes that improved defensive work is imperative at the Emirates
The Cottagers have come away from games against Southampton and Reading with a point after conceding last-minute equalisers, while they had to come from behind late on themselves in last weekend's draw against Everton.
Jol believes that their defensive frailty is down to a lack of discipline off the ball, and is looking for improvement when they travel to Arsenal on Saturday.
The Dutchman told the club's official website: "It's difficult because for us, with the players we've got, it's important that we dominate possession. That is not easy away from home.
"We want to be better off the ball and that is something we've been working on. Hopefully we can do better than we did against Everton because that was not what we wanted."

"Arsenal have always been a good footballing team and they will have been disappointed to lose their last league game against Manchester United," he continued.
"But those are two top teams who want to win, and I think they are doing fine."
