Bulgaria: what does Radev’s victory portend?

For Club Z, it is unlikely that Bulgaria’s position within the EU will change:

“As far as our orientation in foreign policy is concerned, it’s all decided already, and even Radev’s pro-Russian remarks won’t change that. We are part of Europe’s inner circle and it would be almost impossible to remove us. … Bulgaria is in the EU, in Nato, in the Schengen Area and in the Eurozone, much more than can be said of Hungary and Romania, for example. It is, of course, possible that Radev, as future prime minister, will embarrass us in Brussels with the odd Russophile remark. … But it’s hard to imagine that he or any other Bulgarian politician will try to take centre stage at the heart of Europe and start playing the rebel.”
