European Parliament President Martin Schulz took to social networks a day before his arrival in Athens on Thursday to warn that the new Greek government “won’t survive long if says ‘No’ to everything.”

Schulz will be the first high-ranking European leader to meet with new Greek Prime Minister Alexis Tsipras after the latter won Sunday’s election. The contacts he’ll have in Athens with the new leftist government are being closely watched elsewhere on the continent.

He posted the a message LinkedIn and also urged all his Twitter “followers” to read it.

“Ready for my trip to Athens and meeting the new Prime Minister” was the way Schulz started the message, before issuing his “advise” to Athens’ leadership.
