It used to be the Greece, then it was the PIGs (Portugal, Ireland, and Greece), then it was the PIIGS (Portugal, Italy, Ireland, Greece, and Spain), and now it seems that the entirety of the eurozone is at risk.
Right now, EU leaders are trying to agree on a solution that is legal based on the terms of individual states constitutions and the EU treaties and one that actually fixes the major problems at the heart of the crisis.
But most of all, they're looking for a plan that their voters will go for.
As you can imagine, they're not doing so hot right now.

1. The costs of sovereign borrowing could spiral out of control.

Yields on Italian sovereign bonds rocketed to record—
and arguably unsustainable—yields last month.
 In the secondary markets, yields on 10-year bonds topped 7.3%,
and sub-par bond auctions have made everyone wonder if Italy has become illiquid.
But this is not just happening in the PIIGS anymore—borrowing costs rose sharply in
 France, Belgium, Austria, and even Germany at the end of last month,
 suggesting that no country is safe from the effects of the crisis.

2. Contagion from Italy and Spain.

The Italian and Spanish economies are too big to fail and too big to save. Italy's 120% public debt-to-GDP ratio second in size only to Greece among euro area countries, and Spain's public debt is rapidly expanding to prop up an overly leveraged private sector.
If one country falls it affects bond yields elsewhere in Europe and lending throughout the banking system via contagion. These effects would be particularly strong if the failing country were Italy or Spain. EU leaders must find some way to reassure markets that both countries' debt issuances are truly risk-free in order to stem rising borrowing costs that could render finding funding in the open market impossible.
