Cristiano Ronaldo missed a second-half penalty on the night he became his country’s record appearance holder as a hugely frustrating match for Portugal and their captain in Paris ended goalless to leave Group F wide open.
Ronaldo struck the base of the post with his spot kick after Austria defender Martin Hinteregger had wrestled him to the ground and later headed home only to be denied by the offside flag.
But huge credit for Austria’s point must go to keeper Robert Almer, who made a string of sensational saves.
Portugal now has a must win match against Hungary on Wed night if they are to Qualify.
Belgium on the other side won with a convincing 3 goals after their loss to Italy. Romelu Lukaku scored twice and Axel Witsel once as Belgium got off the mark at Euro 2016, comfortably beating Republic of Ireland 3-0 in Bordeaux.
Belgium had failed to impress during their opening game of the tournament, losing 2-0 to Italy, but Marc Wilmots made three changes to that side, with Mousa Dembele and Yannick Carrasco replacing Radja Nainggolan and Marouane Fellaini in midfield, while Thomas Meunier came in for Laurent Ciman at right-back, and it worked a treat as they emphatically swept Ireland aside.
