Last year's beaten finalists Arsenal avoided disaster with a 0-0 draw at FC Porto which was enough for both teams to go through to the Champions League knockout stages.
Neither team looked to be trying too hard, knowing that both would qualify from Group G with a point even if CSKA Moscow won in Hamburg.
Nevertheless Porto showed glimpses of excellence, with midfielder Quaresma busy throughout the night. He beat Arsenal keeper Jens Lehmann to twice hit the post in the second half and the Gunners could so easily have been two goals down.
Quaresma had earlier caught the eye in the first half when Arsenal were often uncharacteristically sloppy by losing possession in midfield through lapses in concentration.
Arsenal's most exciting move in the first half came when a cross by Alexander Hleb was blocked by Brazilian Pepe after an impressive build-up. Porto even looked to be showboating on occasions.
No English team had won at Porto in European competition in eight previous attempts and this result made it nine.
When the second half began, Arsenal's Cesc Fabregas immediately darted towards Porto's area but his attempted pass was blocked.
However the first real goal threatening move of the half came three minutes after the restart. Lisandro Lopez sprinted down the right flank and he pulled the ball back for Quaresma whose first-time shot easily beaten Lehmann, only for the ball to bounce back off the foot of his right hand post.
Arsenal had not learned their lesson and in the 58th minute there was deja-vu. Quaresma, the best player on the pitch and exuding confidence, again beat keeper Lehmann and again the ball smacked off the foot of his right hand post.
Porto's heads were up after those clear chances and they started to stroke the ball around the park nicely, but Arsenal's defence held firm as moves broke down on the edge of the box.
Ljungberg darted into the box in what promised to be a dangerous move midway through the half but he just could not get a shot in.
News came through that CSKA Moscow were leading at Hamburg SV which meant that the losing side in this match would be knocked out if the result stood in Germany.
However the match ended as it had threatened to finish right from the beginning - goalless - and Hamburg won 3-2 anyway.
