Brazil captain Thiago Silva says we will see a "better Neymar" at this World Cup after injury hampered his past two tournaments.
Neymar missed the 2014 semi-final with a back injury, and struggled for full fitness during the 2018 tournament after foot surgery earlier in the year.
However, he arrives in Qatar fully fit and having scored 15 goals in 20 games for Paris St-Germain this season.
Brazil will play Serbia at 7am tomorrow.
Meanwhile, Switzerland will take on Cameroon at 10 tonight.
South Korea will face Uruguay at 1am tomorrow and Portugal battles Ghana at 4am tomorrow.
