According to Neymar's father, the Brazilian superstar will be "back to his best" in time for the World Cup championship game.

After defeating Switzerland and Serbia in their opening two games in Qatar, the Selecao has already advanced to the round of 16 and only needs a point to take top place in their group.

Neymar was forced to sit out until the knockout rounds due to an ankle injury he sustained during the matchday one triumph over Serbia.

Despite Neymar's uncertain return date, Brazil are still among the favorites to win the competition.

The forward, though, will reportedly return in plenty of time for the World Cup final, provided Brazil advances that far. He is just two goals shy from tying Pele's record total of 77 goals for Brazil.

The most crucial factor is that he can return to the field and perform at his top, Neymar Sr remarked in an interview with talkSPORT through an interpreter.

"When he was injured before and he came back again he was at his best. He will do his best.

"Everyone knows Neymar is very important, a great influence on the field and [on] all his colleagues. When Neymar is on the field it's totally different because he's number one. We know Neymar's importance to the group.

"I believe Neymar will be in the field again in the final match and he'll do his best to win the World Cup together with his colleagues in the Brazilian team.

"He'll do his best to help them and together win the competition."

Brazil face Cameroon in their final group game. They will meet the still undecided Group H runners-up if they do finish top.

The Selecao are aiming to win the tournament for the first time since 2002.
