We round up Tuesday's talking points from Russia as the hosts impress again, Mohamed Salah scores on his return from injury and Neymar gives Brazil potential cause for concern...
Each day during the tournament, we will be pulling together all the big stories and best reaction right here in a nutshell, so you do not miss a thing.
Here are the highlights from day six at the World Cup...
Japan secured their first World Cup victory on European soil as Yuya Osako's header earned a 2-1 win over 10-man Colombia in Saransk.
Jose Pekerman's side suffered the worst possible start after Carlos Sanchez was sent off for handling Osako's goalbound shot with Shinji Kagawa on hand to calmly slot the resulting penalty (6).
But Colombia responded well to the setback to deservedly equalise through Juan Quintero's clever free-kick under the wall (39). Japan were the dominant side in the second period and after David Ospina had twice been forced into good saves, Osako rose to head in the winning goal (73) to spark emotional scenes both on the bench and in the stands of the Mordovia Stadium.
Senegal claimed their first World Cup win since 2002 with a shock 2-1 victory over Poland in Group H.
In a tightly-fought contest, Thiago Cionek's unfortunate own goal (37) handed Senegal the lead.
Senegal doubled their advantage through M'Baye Niang (60) who capitalised on a poor backpass from Grzegorz Krychowiak to score his first international goal.
Krychowiak pulled a goal back for Poland with a powerful header four minutes from time, but Senegal held on for victory as they begin their World Cup campaign in style.
Hosts Russia roared to a 3-1 win over Egypt in St Petersburg to put themselves on the brink of the World Cup last 16.
Ahmed Fathi's calamitous own goal (47) broke the deadlock, before Denis Cheryshev (59) and Artem Dzyuba (61) struck twice in two minutes to settle the Group A clash and move Russia onto a maximum six points after two games.
Mo Salah, who was included from the start, pulled a goal back from the penalty spot with 17 minutes left, but it will take an unlikely series of results to prevent the hosts from progressing while Egypt's tournament is probably over after two straight defeats.
Egypt had hoped the return of Mohamed Salah could keep their World Cup hopes alive, but it was not to be.
Instead it was hosts Russia - much maligned before the tournament - who moved close to a place in the last 16 with a 3-1 win in St Petersburg. The key period in the game came around the hour mark as Russia scored twice in three minutes to help secure another impressive victory.
Salah, meanwhile, did not look 100 per cent on his first appearance since injuring his shoulder in the Champions League final with Liverpool. He did manage to pull a goal back for Egypt when he converted a penalty which he won in the 73rd minute, but he could not impact the game further.
Could Brazil's World Cup hopes be about to take a major hit?
Their star player Neymar left training early on Tuesday after feeling pain in his right ankle and will undergo physiotherapy, according to the Brazilian Football Confederation.
The 25-year-old missed an outdoor training session on Monday after feeling pain from Brazil's opening match against Switzerland in which he picked up a knock after being repeatedly fouled.
"He was feeling pain thanks to the large number of fouls he suffered in the Switzerland game," a Brazil spokesman said on Tuesday. "He complained of pain and so he went to physio and he will train normally tomorrow."
Meanwhile, suspended former FIFA president Sepp Blatter arrived in Moscow for a World Cup visit at the invitation of Russian president Vladimir Putin.
Blatter posed for photographs on his arrival Tuesday at a five-star downtown hotel. The 82-year-old is banned from official football duty until October 2021 for financial misconduct during this 17-year rule. But FIFA's ban does not prevent him attending games and he is expected to see Portugal play Morocco on Wednesday at Luzhniki Stadium.
This is Blatter's first public appearance outside his native Switzerland since July 2015 when the World Cup qualifying draw was conducted in St. Petersburg.
Tunisia goalkeeper Moez Hassen has been ruled out of the World Cup after dislocating his left shoulder in the 2-1 loss to England on Monday.
The team posted the injury update on Twitter, saying Hassen was the "victim of a dislocation" and the injury was "very bad news for Tunisia." Hassen collided with Jesse Lingard in the fifth minute of the match in Volgograd.
The first member of Japan's royal family to visit Russia in more than a century got to witness an historic World Cup result on Tuesday.
Princess Hisako of Takamada was at the Mordovia Arena in Saransk on Tuesday to see Japan beat Colombia 2-1. It was the first time a team from Asia has beaten a South American opponent at a World Cup.
Princess Hisako's visit is the first such trip by a Japanese royal since 1916.
