Yeah I just checked, he did a Leicester in Romanian league and won the title with relegation candidate team.
They put up a good show in the UCL too, but the owner got greedy and took all the prize money the club made, and put it into his pocket. Petrescu had a decent run in Russia too, but after that it all went downhill.
I remember the news here when he was on a high: Abramovich wants to replace whoever was being fired at the time at Chelsea with Dan Petrescu. He was a bit like Conte when it comes to expressing himself on the sideline, with a bit of good old romanian "everyone is against us, trying to rob us" mentality. Good manager though.
