The Gunners go into the sixth round of fixtures at the top of the table, having won their last four Premier League games after losing on the opening day against Aston Villa, and, while the Dane is expecting a tough game at the Liberty Stadium, he wants his team to be more clinical.
"It will be important for us to stop the balls between the lines because they are a very dangerous side with attacking players. That is a key area," he told reporters, "but we also have to take our chances.
"When you create so many chances – and that is a major positive – against huge sides like Liverpool and Valencia, you need to score. We have an average of two goals a game but I think we can do better. We need to take our chances more often - we saw that in the Capital One Cup in midweek [losing to Birmingham City] and we were made to pay for that."

"We had some good games last season," he enthused. "From our point of view, we always remember the league game in London which we won 2-0 but we also had good games [at home] too - in the cup and in the league. I am looking forward to a very exciting game."
The Dane also took time out to praise the Gunners, whom he feels have bounced back well from their opening-day disappointment.
"It's great what they have done so far this season. They lost the first game and then people were saying they would find it tough this year," he explained, "but they have gone on to win their next four league games and some tough European games and now they are top of the league.
"For us, this is the third game at home in the league – we have faced the champions [Manchester United] and then the leaders [Liverpool]. Now we face another club that is top of the table so it's been tough but this is what the Premier League is about."
