Germany and Portugal are facing UEFA fines following their European Championship opener on Saturday.
UEFA announced on Sunday they had begun disciplinary proceedings against the German Football Association over the behaviour of their fans during the country's 1-0 Group B win in Lviv.
Supporters threw screwed up paper at Portugal's players during some corner kicks at the Arena Lviv and let off a smoke bomb in the stands. They were repeatedly warned over the public address system that such acts could result in their ejection, sanctions for their team, and even abandonment of the match.
