Sydney coach Paul Roos is grateful his team doesn't have to play Collingwood again next week and admits the Magpies have his team's number at present.

Collingwood strolled to their fifth successive win over Sydney in a comfortable 29-point AFL victory over the Swans at ANZ Stadium.

Roos said his forward line really struggled after his team produced a paltry return of just 6.14, including two goals to three quarter-time, to Collingwood's 11.15.

It was the third straight year Collingwood have beaten Sydney in the split-round clash at the venue and Roos conceded Collingwood had the upper hand over the Swans.

"I think so at the moment, we don't have to play them next week which is pretty good, or the week after," Roos joked.

"We have to play them at the end of the year (round 21 at Telstra Dome), so we'll have to change a few things.

"They enjoy playing against us, they play really well against us. That happens, certain teams play well against other teams."

Roos was pleased with his team's defensive effort, particularly All Australian back Craig Bolton.

"We tried to plug the holes with him on just about every forward that was on fire and he was able to snuff them all out, he was outstanding," Roos said.

The Swans kicked just 1.5 in the first half and Roos lamented a number of wayward shots for goal which prevented his team from applying scoreboard pressure.

"Our forward line tonight really struggled and that probably was the difference in the game," he said.

"They got some really, really good goals out of Travis Cloke and Dale Thomas (three goals each), but we just couldn't seem to get anything out of our forwards."
