The same Koller that scored yes but I think it says it all if you think he was "lost abysmally". There were a lot of factors in that goal. O'Shea's stupidity in throwing the ball to the Czechs to take a quick free kick and strolling back, leaving McShane one on one with Koller. He kept with Koller and pushed him out wide. Henderson's positioning was poor.
Of all things I can't believe you'd actually question is concentration for that goal. I find that very strange.
