Isn't that the eternal unanswered question? We could fight untill the end of times about it
But you're right, Real has a better form right now, and Bayern are now without Lothar Matthaus, so it will be much closer. But as we have seen with Barça, form can come and go by the day. I think it will be exactly the same as with Real - MU. Both are able to win, and in the end the one that gets least arrogant wins.
But I think we agree about the fact that a finals between Barça and Real would be the best final ever, whatever the result may be.
