Varoufakis is clearly an educated guy. I often find myself agreeing with his analysis, but disagreeing with his solutions though.

But one thing he said last night was bang on.

"let's have a little negotiation between us. First you're going to give me everything I want. Secondly we will discuss that which you want".

The agreement to the sequencing of talks by May was a huge mistake and set the tone for the rest of the negotiation period.
