Firstly, 4 points is a huge advantage, those who think otherwise are simply lazy - it's enough to look at how many points the two leaders lose on average per game to realize that 4 points is a lot.
Secondly, Dortmund is a bad example - they always have a large randomness of results no matter what. Even when they are not under potential pressure, they may unexpectedly lose to an underdog. Bayer, after they were led by Xabi, plays smoothly and I don’t see any prerequisites for mental problems (after all, this coach knows everything about this and will be able to support the team psychologically if necessary).
Mostly I have to agree with you.
But you are forgetting 1 thing, history. In Germany Leverkusen has a nickname, "Vizekusen" ( vice ) .
It's because several times in their history they have been there, with a chance to win it all, but they always failed.
Of course this is a different team now but still it might get to their head.
Also 4 points, that's not a lot if Bayern actually starts winning. They still play each other so even if they both win all other games and Bayern beats Leverkusen it's only 1 point. And we know what can happen if the nerves show themselves, we saw it with Dortmund last year.
You are so close, you can feel the cup in your hands already, and then it all comes crashing down.
Actually I am still convinced Leverkusen will throw it away and Bayern will win. I hope I am wrong because I am a Dortmund fan for 30 years now, and I if not BVB I want to see any other team on top other than Bayern, and Schalke of course but they are not relevant playing in the 2nd league.
Yea, bayern leverkusen behaves like arsenal of EPL no doubt but I don't think that it will be as usual this season, if we are to put recent events into consideration, I will say that Leverkusen deserve a kudos this season, there previous match with Leipzig made me to believe that this team is heading somewhere this season, I never expected such a come back in the second half of that match, bayern leverkusen displayed a good performance in that game and they won, as it is now, I don't see bayern leaving any stone unturn, sure the game of soccer can be tricky most time but in all the checks been done, bayern has a great edge this season because of prepared and serious they are in their gaming.
