Iceland need to improve their attacking play if they are to have any chance of reaching Euro 2016's last 16, according to midfielder Birkir Bjarnason.
Basel's Bjarnason, who scored his country's historic first ever goal in the opening 1-1 draw with Portugal, rued Hungary's late equaliser in Marseille, where another 1-1 draw left Iceland on two points.
"We have two points and we will have to go for the win in the last game," said Bjarnason. "Three minutes from the end is really disappointing."
In the 87th minute, Birkir Saevarsson's own goal had cancelled out Gylfi Sigurdsson's first-half penalty.
Iceland are second in Group F, ahead on goals scored of Portugal, who could only draw 0-0 with Austria in Sunday's late game after Cristiano Ronaldo missed a second-half penalty.
Bjarnason said: "We played with a rock solid defence for 87 minutes and then we lost a little bit of concentration and they scored. Overall, we played an OK game -- not good offensively, but defensively it was good."
Austria recovered from losing their opener 2-0 to Hungary by keeping Portugal at bay and are in with a chance of qualifying if they beat Iceland at the Stade de France on Wednesday.
"Austria are a good team but we are a good team as well," said Bjarnason. "We have to play better if we want to beat them and we will."
In Marseille, Iceland were clinging on to their lead as Hungary pinned them back.
"We have shown that before in the group that we can play football," said Bjarnason. "We didn't do that [against Hungary] and it was not good enough.
"We have to change that in our game for the next match. We have to play more football and we know that."
