Munich - Bayern Munich Juergen Klinsmann, attempting to lift his side after two successive defeats, said Monday criticism made him work even harder.
"Criticism makes me even more ambitious. I am the sort of person who works even harder when things aren't going so well," he said.
Klinsmann has to pick his team up after a 2-1 home defeat to Cologne ahead of Wednesday's Champions League tie at Sporting Lisbon.
Three defeats in four matches have put Klinsmann back under pressure at Bayern where a number of players have called for a more defensive approach.
