Tottenham captain Hugo Lloris says the players let the club down last night.
Mauricio Pochettino's side were obliterated 7-2 by Bayern Munich, who scored five goals in the second half of the group game on Tuesday night.
"I feel really bad for the fans mainly because we gave up a little bit too easily and the score was even worse," Lloris said.
"It is a night that affects a lot. Now it's about character, clearing the mind.
"The next two games against Red Star will become even more important, we cannot lose any more points."
