Don't be naive with this Chelski being the champs - look at how they were and are performing this entire season, forget about what happened last year when they also had Drogba. Around the time you beat them, they were losing to mediocre teams in the EPL being unbalanced and all, trying to find room on the field for all the expensive toys they had bought in the summer, while selling off their cover mids.
and Shakhtar? are you kidding me? You and Chelsea made them look good - you saw what happened to them when a BVB with some players missing got their hands on Shakhtar, didn't you? This same Shakhtar - same coach, same players - finished dead last in their CL group last year featuring Apoel, Zenit and a weak Porto team (worse than this year's Porto). Then you think all of a sudden they turn into a proper barometer for how good Juve is this year? Shakhtar has and will always be nothing more than a decent sparring partner for the good teams in Europe.
you guys are kidding yourselves if you think you've proven to be ready for the CL just because of a close win vs Shakhtar, a win vs Chelski (conditioned by a deflection goal that opened up the game for Juve) and eliminating a naive Celtic team who thought they had any chance of beating you in an open game. The real test is yet to come.
