I thought Fiorentina made a big mistake in trying to play normally instead of playing the conditions.
They should have made a big effort to get a second goal when they had the wind at their backs in the first half, instead they sat back and let Bayern keep the ball quite easily.
Fiorentina gave it a good go, but they were always going to struggle to hold on when they had to play against the wind in the second half when they had such a narrow advantage.
I also thought it was a huge mistake by Fiorentina for Van Bommel's goal. Three or four players went to Ribery and not one of them even made a challenge. When so many players are out of position, you must stop the attack, and they failed to do that, and Bayern took advantage.
Fiorentina were rather naive to twice allow Bayern to race up the pitch and score immediately after Fiorentina themselves had scored.
