Brazil coach Tite has admitted that he knows little about World Cup opponents Cameroon, who have been drawn alongside the five-time champions, Serbia and Switzerland in Group G.
The clash between Brazil and Cameroon will be the last group game for both, so allowing both sides to learn a little more about each other in Qatar itself.
Cameroon, who reached the Africa Cup of Nations semi-finals on home soil earlier this year, qualified for Qatar in dramatic fashion when scoring a goal four minutes into additional time of extra-time against Algeria on Tuesday.
The Algerians have since asked Fifa to replay the match, citing "scandalous" refereeing which "distorted the result".

The record eight-time African World Cup qualifiers have played Brazil six times, losing every match bar a 2003 Confederations Cup game they won 1-0 - a victory later overshadowed by the death of Marc-Vivien Foe at the same tournament.
Cameroon lost 4-1 to then hosts Brazil in the 2014 World Cup, the last time the Indomitable Lions contested global football's showpiece event.
Tite and Brazil last played the five-time African champions in a 2018 friendly in England where Everton striker Richarlison's solitary goal proved the difference between the two sides.
Clarence Seedorf coached a Cameroon that featured, among others, Bayern Munich's Eric Maxim Choupo-Moting and Lyon striker Karl Toko Ekambi, who scored five goals at the recent Nations Cup.
"I have no deep knowledge about Cameroon," Tite told BBC Sport Africa.
"I have a general idea, but I can't give you specific details as I was geared towards the World Cup qualifiers and in the direct preparation of the team."
