Gregoritsch prodded home David Alaba's cross in the 78th minute before Arnautovic struck in the 89th, as Austria earned a first win at the Euros at their seventh attempt, and their first victory at a major tournament since the 1990 World Cup.

The Austrians had possession and circulated the ball well but struggled to break through until Marcel Sabitzer floated a perfectly-timed cross to the far post.

Stefan Lainer latched on to it, leaping into the air to beat keeper Stole Dimitrievski from a tight angle.

The North Macedonians, however, drew level with their first chance of the game 10 minutes later when defender Martin Hinteregger's clearance first bounced off the back of Sabitzer and keeper Daniel Bachmann then let the ball slip for captain Goran Pandev to slot in.

That was his country's first ever goal in a major tournament and the forward, who has 38 goals in 120 appearances, also became the second-oldest player to score at the Euros, after Austria's Ivica Vastic, who was 38 back in 2008.

The Austrians continued to struggle with a hard-working North Macedonia defence after the break, forcing coach Franco Foda to switch to a two-striker formation, bringing on forwards Arnautovic and Gregoritsch.

The move paid off in style when Gregoritsch timed his run to perfection to tap in before keeper Risto Jankov got his hands on the ball.

Arnautovic pounced on a defensive mistake to round the keeper and seal the Austrians' first tournament win in 31 years.

Austria resume their campaign against Netherlands in Amsterdam on Thursday, while North Macedonia stay in Bucharest to face Ukraine.
