Bayern Munich coach Jurgen Klinsmann admitted Saturday's 5-1 defeat to Wolfsburg had dented morale ahead of Wednesday's Champions League quarter-final in Barcelona.
The defending Bundesliga champions fell to their biggest defeat in seven years against the new league leaders to fall three points off the pace at the top and once again miss the chance to rise to the summit for the first time all season.
But more importantly, it was the worst possible preparation for a tricky trip to Spain this week.
"This defeat hurts, also in view of the game in Barcelona," admitted Klinsmann. "To fly back to Munich on the back of a result like this is anything but comfortable."
However, Klinsmann promises his side will bounce back immediately because a similar defeat on Wednesday would leave them with little chance of reaching the last four of the Champions League.
"We have got to look forwards and move up a gear as quickly as possible," he said.
"Of course we will discuss the errors we have made, but we will be focusing our attention on Barcelona.
"We are all professionals and part of that means we must lift ourselves, even after a hammering.
"We will get up again and play a good game in Barcelona."
Indeed, Bayern's form in Europe this season will give them confidence, despite yesterday's crushing defeat.
They defeated Sporting Lisbon 12-1 on aggregate in the last round while they boasted the best record of all 16 qualifiers from the group stage.
A positive result at the Nou Camp would also enable them to rediscover self-confidence ahead of next weekend's Bundesliga clash with Frankfurt.
"All is not lost," added Klinsmann. "There are still enough games to play, but certainly the atmosphere is anything but good. We have got to digest this."
Wolfsburg manager Felix Magath earned one of the sweetest victories of his managerial career against the club who fired him despite winning back-to-back league and cup doubles, yet he still refused to talk about the title.
The Wolves have now won eight consecutive Bundesliga matches and have dropped only two points in 13 home games, but not even securing a place in the Champions League is on Magath's mind.
"Our aim is still to secure fifth position," he said.
