Where's your support going? Here's BBC Sport pundit Mark Lawrenson's prediction to help you...
"Despite his pre-tournament injury worries, Cristiano Ronaldo should play for Portugal - but it is hard to see him being at anything like full fitness.
"I am going to throw in a bit of a curveball here because I don't think Portugal will get out of the group. Ronaldo has had a long, hard season and it has taken its toll. And if he is absent at any stage, then about 50% of his country's chances disappear with him."
Lawro's prediction: Germany 1-0 Portugal
