Juventus guardian Gianluigi Buffon has warned his teammates that the upcoming Champions League clash at Bayern Munich is a no-nonsense encounter. Juve will visit the Bavarian giants on Wednesday after being held at home by Bordeaux in the first round, and Buffon insists that the game is for the fearless. "It is a match for fearless hearts, for players who must not have any fear or uncertainties," the Italy keeper told Juventus' official site. "These are the matches for which it is worth it being a footballer, because you are playing against very strong teams in extraordinary contexts. "On paper, at the beginning of the Champions League, Bayern were our number one rival in the group."
