Brazil assistant coach Cleber Xavier has described Senegal as a "well trained and strong" team whose type of play is fashioned around Liverpool forward Sadio Mane.
The five-time world champions and Africa's top-ranked side clash in an international friendly match at the National Stadium in Singapore on Thursday.
It would be the first ever meeting between the two sides as Brazil are preparing for the 2022 Fifa World Cup qualifiers, while Senegal would be gearing to get their bid for a place at the 2021 Africa Cup of Nations underway in November.
