Eurozone finance ministers are due to meet today to discuss the Greek bailout program.
The meeting is seen as the final chance for Athens and its international creditors to reach a final agreement before a June 30 deadline.
Greece needs to strike a deal with its creditors before then, or face a default crisis on payments of 1.6 billion euros due to the IMF.
Though both sides have said that time is running out, the dialogue has been in a deadlock.
German Foreign Minister Frank-Walter Steinmeier says he does not expect any new proposals from Greece.
"I noticed that Greece doesn't have the intention to come up with new proposals at the finance ministers meeting coming up on Thursday. That makes time even tighter."
On the other side, Greek Finance Minister Yanis Varoufakis says he is not optimistic about possible outcomes.
Question: "Can there be an agreement tomorrow at the Eurogroup meeting?"
"I do not believe so. Eurogroup meetings are not designed to stage fresh conversations that have not been prepared in advance. I do not believe this preparation has taken place and also it's my considered opinion that now the agreement has to be reached at a level of political leaders, heads of state, prime ministers, chancellors."
