What stream did you order? I couldn't watch the game last night coz all free stream were shit...
would appreciate it if you guide me through

int:
I don't know who provides CL coverage in Germany so I can't direct you to their own site but it also works directly via the uefa website.
On matchdays go to the uefa site, preferably a while before the game starts. Right hand side of the site there's a colum "live streaming" with a list of all the CL games.
When you choose the Juve game you should be directed to a page where you can choose your local provider (first you need to register if you haven't used this service before). I had the choice between 2 providers, don't know how many choices you have in Germany, maybe just one.
Choose your provider, you'll be directed to the payment screen (Visa card in my case, but this might be different for you). Take care of this and you'll get a confirmation screen (also by e-mail). If it's almost game time you'll be able to start the stream. If not you'll get a screen saying live coverage will start soon.
Yesterday the stream started about 15min before kick off time.
Hope this helps, feel free to ask if something is not clear.
