Saturday's World Cup qualifying reports
Wales 1-1 Serbia
Wales' hopes of qualifying for the 2018 World Cup were dealt a severe blow as Aleksandar Mitrovic's late equaliser for Serbia denied them victory in Cardiff.
Despite a strong start from the visitors, Gareth Bale fired Wales ahead after the tireless Hal Robson-Kanu forced Serbia's Matija Nastasic into a mistake.
An occasionally scrappy but absorbing encounter saw chances at both ends and, just moments after Bale hit the post, Mitrovic headed in to stun the Cardiff City Stadium into silence.
With the Republic of Ireland's win in Austria taking them top of Group D, Serbia and Wales stay second and third - two and four points behind Martin O'Neill's men respectively.
Austria 0-1 Republic of Ireland
The Republic of Ireland enjoyed a first victory over Austria since 1963 to move top of Group D, boosting their chances of qualifying for the 2018 World Cup.
James McClean struck early after the break with a super goal from an acute angle to surprise an Austrian team which had dominated the opening 45 minutes.
The victory, Ireland's first over Austria in nine matches, leaves Martin O'Neill's men with 10 points.
Early pace-setters Serbia, who have seven points, play Wales at 19:45 GMT in Cardiff and anything other than a victory for the Serbians will ensure Ireland end the year as group leaders.
