U.S., South Korea through, Portugal out.
Donovan's (unfairly) disallowed goal in the fourth minute pretty much doomed the U.S. Poland scored on the restart and that was that. For the remaining 85 minutes, Poland played the defend and counter game which they did well.
I don't know about the clinic part, Y Lifter. Poland had a dream start, that's all. They certainly relished having nothing to play for. The U.S. dominated the match with 65% of the possession and 15 shots to Poland's 7, but it was all set up by the two early goals.
Sorry about Portugal, Varnsen, but again don't blame the U.S. Your guys had been playing together since 1988 or so. They should have been ready to play from the start, but seemed to be looking ahead to the later rounds.
What should have happened is South Korea should have beaten the U.S. and then Portugal would have advanced on goal differential, but still - if Portugal had taken care of their own business they wouldn't be checking their bags for Lisbon.
