As a Gooner, it's basically choosing the lesser poison.
If Chelsea win, I have to suffer watching JT and Lamps lift the trophy and claim the first London side to win the UCL. But then I get to watch Sp*rs toil in misery every Thursday in the Europa League, sans Bale and Modric
If Bayern win, I get to watch JT cry, and save the chance for the Arsenal to lift it for the Londoners first time. Then I'm banking on Sp*rs bottling it in the qualifiers.
...
Yeah, I'm going for Bayern on this one
