In a book “Presidents should not talk about such things” Hollande confesses to have received a phone call by Putin who said:
“I want to give you this information. Greece asked us to print Drachmas because they have no longer a printer for this. I want to tell you that this is something [ apparently the Grexit] that we do not want.”
The book author note that this Greek request was a proof that Greece was thinking to exit the eurozone.
