Against FCK it was a slow start, rather than an overall bad performance. It was nothing like the lifeless performance we showed against Torino, for example. We remember the terrible result, but we forget that for most of that match we played exactly as we should have. The ball just didn't want to go in.
I mean, just look at UEFA's team of matchday 1 and the ratings of the players:

The FCK keeper has a rating of 9.0, which makes him player of the round, sharing the first place with Messi who scored a hat-trick, and with a better rating/performance than the other hat-trick hero, Ronaldo.
If we play the way we did against Chievo or Torino, we probably won't win. But if we play the way we did for most of the match in Denmark, the Turks don't stand a chance tonight. Their keeper won't perform the same miracles as his colleague from FCK.
