David Alaba was pivotal throughout, providing the crosses for both Janko's goals before curling home the third, with Martin Harnik slotting the ball into the net in injury-time to complete the win. It was nothing more than Austria deserved as they look to make up for a stuttering start in Group C which had seen them take just one point from two games.
The pair shared a 0-0 draw last time out but with both sides shooting from distance in the early stages a repeat did not appear likely.
The visitors were twice grateful to Andrey Sidelnikov, first the goalkeeper parrying Martin Harnik's drilled right-footed shot before collecting Zlatko Junuzovic's subsequent header. So, it was no surprise when Austria took the lead in the 23rd minute when Janko headed Alaba's right-wing cross into the goal.
Again Alaba was involved, his right-wing cross headed home from six yards by Janko and it was 3-0 just seven minutes later. This time Alaba was the scorer, curling a left-footed shot into the top left of the goal with Harnik rounding off the rout in injury time.
