nah, Lech wasn't so good either. they just had luck in the games and drawn teams that used reserved against Lech, like Juve and Man City. also it was probably the worst Juve in last 30-40 years, 2x 7th place in Serie A.
and yeah, I can't see Legia beating Celtic. not with these players and this coach.
i thought he played for lech in that season...but you`re right, lech finished second in 2010-2011
Romanian clubs were much more successful from what I remember
not much...the only decent seasons of the romanian teams were 2008-2009, in champions league, when cfr cluj defeated roma on olimpico, draw with chelsea home, and also in 2012-2013 when they finished with the same number of points as galata, but on the 3`rd place...and also steaua bucharest 2 seasons ago
in 2005-2006 we had a quarterfinal of uefa between steaua-rapid bucharest, but that`s a long time ago, and in 2012-2013 steaua almost qualified in the quarters of EL against chelsea, after they eliminated ajax...pretty good for our level, but not much
