Speaking before Portugal faced Mexico in their Group A opener on Sunday in Kazan, Infantino also sent his condolences to the Portuguese people following the forest fire that killed more than 60 people in the country.
Mexico's all-time leading goal scorer Javier Hernandez pulled one back for his side with a classic flying-header in the 42nd minute with both teams going into the break 1-1.
A warm-up match for the 2014 FIFA World Cup in Brazil was the last time these two teams squared off against each other.
Substitute Cedric Soares looked like being the European champions' hero with his 86th-minute deflected shot, but Moreno's header from a corner spoiled the Southampton defender's celebration of his first global goal to snatch a 2-2 draw for Mexico.
"Any team having to face Ronaldo is usually considered second-favourites, and Portugal will believe their superstar gives them a huge advantage over the Mexicans in Russian Federation", the report noted.
"We need to keep believing in ourselves, we know we have a great chance. There is no reason to be concerned, we have to think about the next match".More news: Vidal and Vargas make the difference for Chile after VAR controversy
Host Russia top the group with three points after defeating New Zealand 2-0 in the opening match on Saturday.
Forward Nani scored but a review by video assistants showed a Portugal player was offside in the build up to the goal. "We were always more risky than them, both in our organised play and on the counter attack".
Portugal coach Fernando Santos said it was not the performance he expected from his team.
"Obviously you have team-mates you spend more time with - I have a good connection with Cedric Soares, Andre Gomes, Joao Moutinho, Bruno Alves, Pizzi and Adrien - but the list could go on because they are all my friends and it is a very good group". Despite the fact that the final whistle did not reveal the victor, having recorded in the asset of both teams on 1 point, Mexico still remains the leader of the group, reducing the gap from the nearest pursuer to 3 points. In addition to that, this should be a low scoring game since neither side will want to be too exposed this early in a tournament so the under 2.5 goals also makes sense.
Despite being relatively quiet in the match, Ronaldo won the Man of the Match award, but he declined to attend the post-match press conference that usually accompanies the accolade.
