Republic of Ireland moved four points clear of Scotland in EURO 2016 qualifying Group D as it overcame Georgia 1-0 in Dublin, courtesy of Jonathan Walters's second goal of the campaign.
Stoke City forward Walters notched from close range in the 69th minute to settle an uninspiring contest, and enhance Republic of Ireland hopes of sealing a play-off position at the least.
Thomas Muller struck twice as Germany moved within touching distance of qualification with a 3-2 win against Scotland at Hampden Park.
A breathless first half in Glasgow saw Muller score twice, either side of a Mats Hummels own goal, only for James McArthur to send the sides in at the break level with a crisp half-volley.
Muller was again decisive as his cut-back found Ilkay Gundogan, who swept home a winner for Joachim Low's men nine minutes into the second period.
The triumph means Germany remains top of Group D, while Scotland's hopes of qualifying for a first major tournament since 1998 hang by a thread.
Poland made light work of Gibraltar – Robert Lewandowski, Kamil Grosicki and Arkadiusz Milik all grabbing braces in an 8-1 rout.
Northern Ireland would have sealed automatic qualification from Group F with a win over Hungary at Windsor Park, but the host had to settle for a 1-1 draw thanks to Kyle Lafferty's 93rd-minute effort.
Richard Guzmics reacted quickest to Northern Ireland goalkeeper Michael McGovern's error to put Hungary ahead but Lafferty, who now has seven goals in qualifying, reacted quickest to hammer home into the roof of the net after Niall McGinn's strike had been parried into his path.
Romania's 0-0 draw with Greece ensures Michael O'Neill's side remains top of the pool, while the late Northern Ireland goal will have been music to the ears of Finland, which remains in with a shout of snatching third after a 1-0 win over Faroe Islands.
Miguel Veloso's thumping stoppage-time header spared the blushes of Portugal team-mate Cristiano Ronaldo in Albania, with the Real Madrid man having hit the post from three yards out early on in a 1-0 victory.
Albania had gone unbeaten in Group I, but it may have to settle for third place, although Denmark failed to pull away in second, drawing 0-0 with Armenia.
