Round-up of Monday night's World Cup qualifying action in Europe.
World Cup holders Germany are not yet guaranteed a place in Russia despite making it eight wins from eight with a 6-0 thrashing of Norway.
Mesut Ozil opened the scoring after just 10 minutes and further goals from Julian Draxler and Timo Werner (two) effectively ended the contest before half-time, with substitutes Leon Goretzka and Mario Gomez completing the rout.
Northern Ireland kept Germany waiting for qualification and they remain firmly on course for a play-off spot after guaranteeing second place in Group C thanks to a 2-0 win over the Czech Republic.
First-half goals from the West Brom duo of Jonny Evans and Chris Brunt gave Michael O'Neill's side a fifth successive victory which virtually assures them of a place in November's play-offs.
The eight best runners-up from the nine European qualifying groups go into the play-offs, with Northern Ireland having taken 19 points from eight games as they seek to reach a second successive major tournament and a first World Cup finals appearance since 1986.
San Marino remain without a point after losing 5-1 in Azerbaijan, who scored five goals in a World Cup qualifier for the first time.
Afran Ismayilov (two), Araz Abdullayev and Rashad Sadigov got on the scoresheet for the home side, who also benefited from an own goal from Michele Cevoli. Mirko Palazzi headed a consolation goal for San Marino.
In Group F, England are five points clear of Slovakia with two games remaining after beating their nearest rivals 2-1 at Wembley.
Marcus Rashford went from villain to hero after being dispossessed to allow Stanislav Lobotka to give the visitors a shock lead after three minutes, before providing the corner for Eric Dier's equaliser and then firing home the 59th-minute winner from 20 yards.
Scotland kept their qualifying hopes alive with a 2-0 win over Malta, Christophe Berra heading the opener after nine minutes and Leigh Griffiths adding a second just after the break.
Slovenia, like Scotland, are a point behind Slovakia after thrashing Lithuania 4-0, with Josip Ilicic scoring from the penalty spot in each half before late goals from Benjamin Verbic and Valter Birsa.
Poland regained control of Group E thanks to a 3-0 win over Kazakhstan, which came hours after Denmark had temporarily taken over top spot following a 4-1 win in Armenia.
Arek Milik, Kamil Glik and a penalty from Robert Lewandowski secured all three points for Poland, who are three points clear of Montenegro and Denmark.
Stevan Jovetic scored in the 75th minute to give Montenegro a hard-fought 1-0 home win over Romania, while a Thomas Delaney hat-trick and a superb free-kick from Christian Eriksen saw Denmark come from behind to win following Ruslan Koryan's brilliant opener for the home side.
