I think it's difficult for Macedonia to give Portugal a red card. Only if it was a counterattack in which Portugal was caught completely off guard. I find this unlikely. Macedonia is quicker to receive yellow cards, or in extramas red situations, than Portugal receive a card. Teams that play in a very defensive style are more likely to receive cards.

But that will also depend on the style of the referee. And in this game we will have an English referee, and these referees usually like to let it play, so I don't think there will be many cards.
