The Cottagers make the short trip to North London on Saturday following last weekend's 2-2 home draw with Everton and the Dutch boss wants things to be a bit tighter when his side is not in possession.
"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," he told the club's official website.
"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."
