Bosnia international Dzeko revealed in February that he "would love" a return to Germany - the powerful centre-forward enjoyed a successful four-year spell with Wolfsburg between 2007 and 2011.

But Dortmund general manager Hans-Joachim Watzke dismissed the rumours linking the club with Dzeko on Tuesday, and Klopp has followed suit.

"This is total nonsense and no more funny," Klopp told SID.

Dzeko scored 85 goals during his time in Bundesliga, and has previously said a lack of appearances for the English Premier League champions could force him to look elsewhere for regular first-team football, despite being City's top goalscorer this season with 13 goals in all competitions.

And Klopp, regardless of a large financial windfall from Dortmund's run in the Champions League this term, insisted a move for the striker, who cost City 27 million pounds, would not be feasible for his club.

Klopp, who previously described Dzeko as "extraordinary", told a press conference on Thursday: "Dzeko is a good player but he is sadly out of our possibilities."

Dortmund's first-choice striker Robert Lewandowski has been linked with a move away from Westfalenstadion, with Manchester United and Bayern Munich reportedly admirers of the Poland international.

Dortmund face arch enemies Schalke in the Bundesliga this weekend, with the potential for crowd trouble in the spotlight after violence at the reverse fixture earlier this season.

Klopp wants to avoid sensationalist reporting of any clashes, expressing his concern over publicity fuelling incidents of unrest between the bitter sets of rival supporters.

"Of course we must not conceal these incidents but we need not let that (get) too big in the media," he said.

"This is the ugly part of such an event.

"Every person looks forward to a derby and only a minimal number of people wants to come to blows. I understand the love for Borussia Dortmund and the love of Schalke. It may be important to win a game. I understand that you are doing everything to win this kind of game. I can understand the disappointment. I can understand all but not the anger. I could never understand something like that. But that has not been able to prevent such incidents which happened.

"We have to report the incidents but we must not (report them) too much. Otherwise that could be a motivation ... Maybe there are people who put that newspaper articles on the wall and say, 'I was part of this fight'. And if that is the case maybe it is better that these incidents become not too big in the media."
