"We spoke about football and the good start of the competition, the good start of the team".
Fulfilling a long-standing personal invitation from Putin to attend the World Cup, Blatter will travel to St. Petersburg to see Brazil play Costa Rica on Friday.
Despite being banned from all football-related activity for another three and a half years, there Blatter was watching Ronaldo light up the Luzhniki Stadium with his fourth goal of the tournament.
The 2018 FIFA World Cup has arrived.
"Today I saw Infantino and Blatter at the stadium, it's true", TASS quoted Sorokin as saying.
Trump will travel to Brussels for a North Atlantic Treaty Organisation summit July 11-12, and the meeting with Putin could take place before that, perhaps in Vienna, reports Reuters.
Russian Federation defied critics and confounded expectation by easing past Egypt 3-1 on Tuesday, all but assuring their place in the last 16 of a World Cup for the first time since the Soviet era.
"But if was the president of Federation Internationale de Football Association I would have said "Welcome to the World Cup, Blatter" - it's only for a few days".
Thankfully, Blatter will be gone by the end of the week, and can stop pretending the World Cup is all about him.
However, Blatter joked about his relationship with Infantino, who is from a neighboring town in the same Swiss region.
Meanwhile, Russian Foreign Minister Sergei Lavrov said Russia was "ready for contacts" with the United States. "How I was received here, television, cameras, people, photographs, and so on", he said.
Blatter has had health scares since leaving office and clearly thrived on the attention from global media and fans in Moscow. "To live these emotions for me was good, to say, 'He is still alive".
Staying in a five-star hotel in central Moscow, Blatter was greeted warmly after his media interviews in the reception area by former Netherlands worldwide Clarence Seedorf. A Kremlin spokesman confirmed Bolton's visit, but he wouldn't confirm Russian media reports that Putin and Trump would get together in Vienna in July, reports the New York Times.
