That being said, the complaint about the boredom of the same draws over and over is falling on deaf ears; this is the FFP era. The big clubs have enjoyed their ascent, and pulled the ladder up behind them. Get used to the same 14 or so clubs joining in year in and year out.
From Spain; Barcelona, Real Madrid, Atletico Madrid.
From England: Chelsea, Manchester City.
From Italy: Juventus.
From Germany: Bayern Munich.
From France: PSG.
Those that will probably jump in and out on a year in basis are as follows:
From England: Arsenal, Manchester United.
From Spain: Athletic Bilbao, Valencia, Villareal.
From Italy: Roma.
From Germany: Borussia Dortmund, Bayer Leverkusen.
From France: Olympique Marseille, AS Monaco.
From Portugal: FC Porto.
From Ukraine: Shakhtar Donetsk.
Such is the shape of modern football, expect to see most of these names year in year out with the rare excursions of FC Basel and the likes of the so called "lower nations" champions sneaking in here or there.
But, anyways, on to this year's draw for the Round of 16!
Up first is PSG versus Chelsea. Before the draw, Mourinho has said he would love PSG in the draw for a multitude of reasons, but I see this more so as a "please not PSG" plea. Regardless, the two sides will be familiar with each other, and with former Chelsea defender David Luiz suiting up for PSG, there will be no love lost between them either. I don't think Zlatan will turn the tide here, although he provides a great matchup versus Terry (and Costa versus Silva as well), but I really think this could be the chance for Lucas Moura to shine. Moura has provided a nice ability in the 1 v 1 on the right, and it's more likely we'll see Filipe Luis than Cesar Azpilicueta. All in all, I wouldn't be surprised if PSG take this, and they're my pick to advance.
Bayer Leverkusen versus Atletico Madrid. I dislike Bayer for sponsorship reasons, (won't go into that), but I think Atletico's style of play, heralded as brilliant, is a bit overrated. Diego Simeone is a mature version of Jose Mourinho. His teams are setup to get the job done, no matter how nasty; and it's worked. That being said, I think they'll do it again. My last impression of Leverkusen versus a Spanish team in the KO rounds was when Messi scored 5. Atletico through.
Schalke again are drawn with Real Madrid, and though Di Matteo orchestrated (?) a miraculous CL run built on grit, determination, or whatever English attributes you want to give to pure luck, there's no way they advance. In fact, I am not surprised if Madrid advance with a double digit aggregate GD here, to be quite honest.
