Tottenham captain Hugo Lloris knows his side have no room for manoeuvre in the Champions League after admitting they gave up during the 7-2 thrashing by Bayern Munich.
Former Arsenal winger Serge Gnabry ran riot, bagging four second-half goals as the German champions became the first visiting side to score seven times at Spurs.
The game ended in farce for the hosts as they checked out and were ripped open on the counter-attack, with Bayern scoring three goals in the final seven minutes.
It leaves the Premier League side in a familiar position of vulnerability in the group stage, sitting bottom of Group B on one point from their opening two games.
They needed a miracle to progress to the knockout stages on their memorable journey to the final last year and while they will still be expected to navigate past Red Star Belgrade and Olympiakos, Lloris says they cannot afford any more slip ups.
'I feel really bad for the fans mainly because we gave up a little bit too easily and the score was even worse,' he 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.'
