Borussia Dortmund chef Michael Zorc has played down the prospect of signing Manchester City striker Edin Dzeko.

Dzeko is being linked with BVB as a replacement for Bayern Munich-bound Robert Lewandowski.

"We are already working to replace Lewandowski, but we like to talk only when operations are to be considered concluded," said Zorc.

"Dzeko and Diego Costa? Not possible. I would like to talk about things, not 'hot air'."
