These are the 18 key players in Greece's crisis negotiations
18.) Lazard Banker Mattieu Pigasse - Pigasse is both a highly regarded financier and a 'pro-market socialist' advising the Greek government on its debt negotiations.
17 and 16.) Finance ministers Luis de Guindos (Spain) and Michael Noonan (Ireland) - Both countries struggled in the euro crisis and are now taking tough stances on Greece, backing the current bailout.
15.) IMF Managing Director Christine Lagarde - The IMF holds a large amount of Greek debt, and its stance holds huge sway around the world.
14.) Bank of Greece Governor Yannis Stournaras - He's responsible for taking Greek banks' case to the ECB, especially crucial if they need emergency assistance.
13.) Minister of Productive Reconstruction Panagiotis Lafazanis - He's a leading light of Syriza's left, and will keep pressure on Tsipras to take a hard line.
12.) EU Commission President Jean Claude Juncker - the most important single figure in the Commission, which makes up a third of Greece's international creditor 'Troika'.
11.) European Commissioner Pierre Moscovici - He's the European Commission's point man on Greek negotiations, and likely to be more friendly to Athens.
9 and 10.) Italy's Matteo Renzi and Pier Carlo Padoan - Italy's PM and finance minister have emerged as Greece's (sceptical) friends in the talks.
8.) German Finance Minister Wolfgang Schaeuble - He's the unofficial leader of the finance ministers taking a hardline stance against Greece.
7.) Eurogroup Chairman Jeroen Dijsselbloem - He's charged with chairing the Eurogroup of finance ministers, who'll decide on any Greek deal.
5 and 6.) France's Francois Hollande and Michel Sapin - France is likely to try and play peacemaker between Greece and Germany, and may have a hand in drafting a deal.
4.) German Chancellor Angela Merkel - Though her finance minister represents Germany in the eurogroup, the final decision on Germany's stance belongs to Merkel.
3.) Finance Minister Yanis Varoufakis - Varoufakis is tasked with representing Greece in the negotiations. His successes or failures at bargaining are crucial to the country's future.
2.) Mario Draghi and the ECB - The position the ECB takes on assistance for Greek banks could save or kill Greece's euro membership.
1.) Prime Minister Alexis Tsipras - Tsipras is now Greece's most important single decision maker. If he and his finance minister disagree, in the end he calls the shots.
