My search found that he indeed beat Douillet in the"Torneo Citta' di Roma" in March of 1996. I found a bunch of wins for this guy, and a bunch of on the podium finishes in high quality International judo competitions. He's going to be tough for Thompson.
I didn't find that he beat Douillet in any other international competitions, but that doesn't mean anything, because most sites list only the top 3 finishers in each weight category, so it's possible that Douillet finished in 4th or 5th or something and I wouldn't know if the two battled. Also, I gave up my search after encountering a number of Romanian and French language websites that were difficult to navigate even with translation on.
I'm certain Douillet lost other international matches. He does have the longest winning streak in World Championship competition though.
That Lungu beat him at all is an eye opener, and when I read his bio and saw the Douillet wins I immediatley realized this guy is NOT to be taken lightly.
Lungu's gonna fuck Thompson up.
