now, with all due respect, hate to bring this one up, cause I know it hurts, but remember 86000 people on the stands at Wembley, but didn't help much, did it?
and do not forget Turkish suporters, there are gzillion Turkey people living in Germany, which is not far from Switzerland, and there are some living in host nations as well, and they are very loud, probably will be louder than Portugese ones...
just my 2cents...
