Video - Nigeria 4-1 Belgium

Nigeria's Olympic team has powered into the final of the men's competition with a 4-1 win over surprise semi-finalists Belgium in Shanghai.

They will now face Argentina after the reigning champions beat Brazil in the other semi.

Olubayo Adefemi gave Nigeria an early lead, with Chinedu Ogbuke Obasi getting the second after half-time.

Obasi scored his second and Chibuzor Okonkwo hit the fourth before Laurent Ciman claimed a late consolation goal.

606: DEBATE Can Nigeria win the gold medal?

Nigeria had been given an ultimatum over their lax approach to the tournament by coach Samson Siasia and the team responded in style.

The so-called "Dream Team" are hoping to match the achievement of their compatriots who won gold in 1996 in Atlanta.

They started with a bang as Peter Odemwingie forced a save from the Belgian keeper in the opening minute of the game.

Adefemi opened the scoring on 16 minutes with a low drive from the edge of the box, which Logan Bailly in the Belgian goal got a hand to but could not keep out.

The score at half-time was 1-0 but in the second period Nigeria cut loose.

Just after coming on as a substitute, Anichebe created the second with a perfect pass for Obasi to fire home.

He missed a glorious chance of his own a few minutes after that, but with 20 minutes to go a huge strike from distance from Obasi put the game beyond Belgium.

Okonkwo grabbed the fourth with an even longer-distance shot, and despite Belgium's late goal from Ciman the Nigerians went through in style.

In the second semi-final, the reigning champions Argentina beat their South American rivals Brazil 3-0.

Sergio Aguero scored twice in the second-half within the space of seven minutes to put them ahead.

He then set up a 76th-minute penalty kick that was converted by Juan Riquelme.

It means the final in Beijng on Saturday will be a repeat of the final in 1996, which Nigeria won.
