"Based on how the conversation took place, I hope that this list of reforms will also come," Merkel was quoted as saying by The Wall Street Journal.
According to the newspaper, Tsipras said after the meeting with Merkel and several other European leaders on Thursday that the talks had moved the situation forward.
European leaders reportedly said that the process of helping Greece could be speeded up if Athens agreed to quick reforms.
Greece's economy is struggling at the moment, with the country's government having borrowed 240 billion euros ($265 billion) from the European Union, the European Central Bank (ECB) and the International Monetary Fund (IMF) under austerity measures imposed on the country.
However, following the January victory in the Greek elections, Tsipras's Syriza party said it would abandon the country's austerity obligations, raising concerns that Greece could leave the Eurozone.
In February, Greece and Eurozone finance ministers agreed to extend the country's bailout for another four months. Under the new deal, Greece should carry out all remaining austerity reforms required by creditors before receiving further financial aid.
