Bayern Munich have said that players were not ordered to stay in their hotel following Tuesday's 2-2 draw at Juventus.
German tabloid Bild has reported that Arturo Vidal, Franck Ribery and David Alaba did not return to the team hotel before the early hours of the morning.
Bayern drew with Juventus after letting slip a two-goal lead, although the German side's two away goals put them in a promising position to progress ahead of the second leg on March 16.
Bild claimed that following the club's traditional midnight banquet -- the club's postmatch meal, which is usually around midnight after an evening match -- Bayern players Vidal, Ribery and Alaba left the team hotel and did not return until the early hours.
The newspaper reports that Ribery and Alaba returned at around 4:30 a.m., while the Chile international was seen back in the hotel at 6:30 a.m..
"There were no guidelines for the players from the sporting leadership," Markus Horwick, the club's media director told the paper. "Every player was responsible for his night's rest."
Horwick added that the early morning training session in Turin at 10 a.m. "was not affected by that" and that the preparations for the Bundesliga match against Wolfsburg on Saturday are all going "according to plan."
In mid-February, Bayern made Sport Bild, who are owned by the same publishing house as Bild, sign a cease-and-desist letter following the publication's claims Vidal had left Bayern's winter training camp in Qatar on several occasions.
