Dzeko is weighing up his future following coach Felix Magath’s decision to join Schalke in the summer.
Arsenal, Manchester United, Sunderland and AC Milan have all been linked with the £17million-rated striker.
“It would be fine to be top scorer in the end, but to win the title is more important,” Dzeko told Bild.
“However, the whole situation at the club has changed due to the departure of Felix Magath to Schalke.
“I am very disappointed that he is leaving and I will have to consider my options at the end of the campaign.”
