One of the lessons we learned in last season's Champions League league phase was that there's little sense in playing for draws. Twenty-six teams won at least three of their eight matches, and 24 advanced. Feyenoord lost by scores of 4-0 and 6-1, but advanced with three wins. Club Brugge lost by scores of 3-0, 3-1 and 3-1 and advanced. Hell, three wins for Dinamo Zagreb damn near overcame a 9-2 first-matchday loss to Bayern Munich.
If Matchday 1 of this year's competition is any indication, teams figured this out, too, because teams were going for it.
