Walters has an ankle problem, Long a dead leg and Whelan a tight thigh muscle, although the early indications are that all three will be available to travel to Vienna when the squad leaves on Sunday afternoon.

However, Trapattoni has indicated that he could make “two or three” changes for the clash with the Austrians as he attempts to keep his side’s mathematical chances of qualification alive.

Both sides are now three points adrift of second-placed Sweden in the race for the runners-up spot, and Ireland still have to go to runaway leaders Germany as the campaign draws to a close next month.
