Portugal (4-4-2): Rui Patricio; Vieirinha, Pepe, Ricardo Carvalho, Raphael Guerreiro; Quaresma, William Carvalho, Moutinho, Gomes; Nani, Ronaldo.
It's been pretty evenly split between these two sides in terms of their previous meetings, with five of those 10 games ending in draws, and Portugal just about edging things otherwise with three wins to Austria's two.
Austria were shocked with a 2-0 loss to Hungary that has left them currently propping up Group F. This is only their second time at the Euros, after thye automatically qualified as co-hosts for Euro 2008.
Portugal come into this match knowing that anything less than a win will be viewed as a disappointment.
