We're on tenterhooks for more than just this game's obvious import as a W.C. opener.
Obviously the victory is job 1, but we're very worried about injury. Portugal has a respectable starting lineup, but no depth. If we lose a starter, (as we already did with Andrade), we have no quality replacements, except for perhaps Simao on the wing and Ferreira at RB.
Angola was Portugal's colony until 1975, so emotion will be very very high on both sides. Added to that, the last time Portugal met Angola in 2001 there were 4 red cards against the Angolans and the game had to be stopped with 20 minutes left and Portugal leading 5-1. It was only a friendly, but very controversial, especially on the Angolan side. This is their most important game, no doubt. If Angola could manage a tie, or a win against us, they'd call this W.C. a runaway success.
