The rest, sorry. Russia, Bulgaria, Poland, Serbia, Cuba. Those are all very good teams, but not good enough to beat Brazil. Not when it counts, at least.
Bulgaria was very close these four times in the WL, so there is a possibility that the next important game between us can be different, when our young players have gathered experience from A1. This is true if we don't have missing players, of course.
P.S. Bulgaria is the only team to beat Brazil with a big pt difference in official games - WL 2006 and WCH 2010 (And don't tell me you played for loss, it will be proof in court )
