I second every word of this sentence above, the Champions League is a very tough and tricky tournamnet and all the teams that make it through can be considered a difficult opponent to handle, notwithstanding, there are teams that are stronger, and are among the favorites, but even such teams cannot underestimate the less stronger teams when they come up against each other. The tournament becomes stronger as the competition progresses, from the QF every game is like a 'Final', and if any teams becomes complacent, they are definitely going to be knocked out.

Having said that, this season there are some teams that look like they will cause the bigger teams problems, i am pretty sure even the bigger teams will be hoping to avoid them in the draws, Napoli, Benfica and Porto are examples of such teams, the tournament is about to get a whole lot more interesting.
