Second-half goals from Marco Torsiglieri and Aleix Vidal changed the complexion of the game after Jonas' opener and left Djukic to bemoan another setback, but he has insisted he will everything he can to turnaround the club's flagging fortunes.

"When you come to a new team there is always the possibility that you could do things wrong. But I am a professional and I will try to put things right."
