NHL 09

If you have any trouble with this, some tips to make this ridiculously easy:

1. Choose the Iserlohn Roosters. Best overall stats, and the best goalie.
2. Choose your opponent to be Team Great Britain. Poor goalie.
3. Before advancing to the gameplay, choose "Game Settings":
* Under Quick Settings, set the Player Advantage and Goalie Advantage sliders all the way to favor your team.
* Advanced Settings: Set your team's aim to "Auto".
* Gameplay Settings, Basic: Set AI Learning to minimum.
* Gameplay Settings, Shooting: Shot Accuracy and Shot Power to maximum.
* Set other settings to taste. I preferred to minimize pokeaways/turnovers.

I'm not fantastic at this game, but I was able to beat GBR 9-0 with these settings.

The easiest way to get this is to have a second controller. Pick any DEL team to play as and have the second controller play as any other team. Make sure the difficulty is set to Pro. Once the game starts, press LB+Back on the second controller to pull that teams goalie, and then score as the DEL team. You can then just wait out the rest of the game. To make it slightly faster, set the period length to 4 minutes instead of 5.

Just like the title says, win with a DEL team.

You can get this from OTP also. Just choose a DEL team from the list. If your team wins, you'll get the achievement.
