Odds in favorites Brazil's favor ahead of tricky Serbia match-up

Brazil are favorites to win the World Cup. They play Serbia in their opening match on Thursday. Tite is unsure about his team selection. Serbia won their last qualifying game and finished top of their Nations League group. Serbia clinched an automatic berth in Qatar with a comeback 2-1 win over Portugal. Switzerland and Cameroon are also in Group G. Brazil are looking for their sixth World cup title. The team is full of young players, 16 of whom made their World Cups debut. Vinicius Jr. is a big question mark. He scored the winner in the Champions League final against Liverpool.
