Hertha Berlin defender Josip Simunic is certain to leave the Bundesliga club in the summer, according to his agent.
The Croatia international's agent, Gordon Stipic, blames a falling out with Hertha boss Lucien Favre for the impasse and claims that the Australian-born centre-back has offers from English, Spanish and other German clubs.
"For me, it is clear that Simunic must leave", Stipic said.
"There is no basis for co-operation and the decision is non-negociable. The reason is the behaviour of Hertha coach Lucien Favre."
"There is interest from England, Spain and Germany, but I will not name the clubs."
Simunic has a €7 million release clause in his contract, which is valid until the end of June.
Bulgaria striker Dimitar Rangelov said he turned down the chance to play in Europe with German clubs and offers from England to join Borussia Dortmund from Energie Cottbus.
"I had offers from Hertha Berlin, SV Hamburg, Bochum and from several English clubs", said Rangelov, who has signed a 4-year contract with Dortmund.
"I know I turned down a chance to play in Europa League next season but I have no regrets", he said. "My personal wish was to join Dortmund and I think I took the best decision."
The 26-year-old Rangelov, Energie's top scorer last season with 9 goals, became Dortmund's third recent signing after Markus Feulner and Kevin Grosskreutz.
