I'm sorry to say, but recent results don't really support that fact. Of course, everything might change, that's why I said "as of now". But as of now, all of those sides would probably give you a hard fight with a good chance of you going out. And winning that things would probably mean beating 3 of those. Which, as of now, doesn't seem very likely. Even if your were to beat 2 of those but losing to the third, you still wouldn't win. We will have to see in the new year.
Also, motivation plays a big role. Do you see that in your side regarding the Europa League? We thought we had the thing in the back when we had to play in the Uefa Cup in 2007/2008, after spending 100 million euros, but a motivated Zenit side wiped the floor with our blokes because they just couldn't be arsed.
