Turkey, who beat the Dutch 4-2 on Thursday, made it two wins from two games as they cruised past Erling Braut Haaland’s Norway in a match played in Malaga, Spain.
Montenegro also have six points from two outings after following their success against Latvia with a 4-1 home win over Gibraltar.
Fenerbahce midfielder Ozan Tufan scored twice as Turkey beat a dangerous Norway side 3-0. Leicester centre-back Caglar Soyuncu also enjoyed a fine performance as he netted the second goal and helped keep Borussia Dortmund striker Haaland quiet.
Earlier in the day, Stevan Jovetic made it three goals in two matches as Montenegro saw off Gibraltar. They sit second in what looks to be a very competitive group, behind Turkey on goal difference.
Russia, World Cup quarter-finalists on home soil three years ago, moved top of the early Group H table with a 2-1 victory over Slovenia, who had started their campaign by beating 2018 runners-up Croatia. Artem Dzyuba’s first-half double proved enough for Russia in Sochi, despite Atalanta forward Josip Ilicic halving the deficit before half-time.
Croatia struggled to find their best form again, but Mario Pasalic’s goal five minutes before the break helped Zlatko Dalic’s men edge out Cyprus 1-0 in Rijeka.
Belarus came from behind to win their first game in Group E, 4-2 against Estonia, who were also thrashed 6-2 by the Czech Republic on Wednesday. The Czechs will be without four key Germany-based players for their match against the world number one-ranked side Belgium later on Saturday, due to Covid-19 travel restrictions.
In Group A, Portugal face Serbia in Belgrade, hoping to improve on a disappointing performance in their opening 1-0 win over Azerbaijan.
