After sneaking through the first two knockout rounds on penalties, Brazil asserted itself as favorite for the 2015 U-20 World Cup with a 5-0 semifinal win over Senegal. The match was never really close: Brazil was two goals up in the first 10 minutes; four goals up by half-time; the fifth came in the 78th minute.
Serbia, on the other hand, went to extra time with Mali - finding its match-winner in the 101st minute.
All three of the Serbs' games in the knockout rounds have required at least extra time to be settled (the quarterfinal against the USA was the only one that went as far as penalties), but they will do well to contain a Brazilian team that appears to have found its scoring touch again.
Before the final, Senegal and Mali will contest the Third-Place Playoff. This will be the only knockout round game that cannot go to extra-time: the teams will move straight from full time to penalties if they are tied after 90 minutes. Mali finished third at the 1999 edition of this tournament; Senegal is making its first appearance at a U-20 World Cup.
Surprisingly, all four of the teams playing on the last day of the competition have got this far without a really dominant scorer. No player for Brazil, Mali, Senegal or Serbia has scored more than two goals so far in the tournament. The top scorers in the competition so far - Hungary's Hence Mervo and Ukraine's Viktor Kovalenko - each have five goals.
The 2015 U-20 World Cup will conclude with either Brazil claiming its sixth title at this level (which will match Argentina's record in the competition) or Serbia lifting the trophy for the first time as an independent nation (Yugoslavia won in 1987).
