Colombia defeated Nigeria 2-0 at the Arena Corinthians in Sao Paulo on Wednesday to reach the quarter finals of the Olympic Games.

Coach Samson Siasia rested goalkeeper Emmanuel Daniel for Daniel Akpeyi and handed Kingsley Madu, Saliu Popoola, Aminu Umar and Ndifreke Udo their first starts since the competition started.

It was the Colombians who got off the starting blocks with the better intent as captainTeofilo Gutierrezpounced on a pass from Diego Pabon to knock it past Akpeyi for the opening goal.

The Nigeria midfield, marshaled by veteran John Obi Mikel, struggled to create chances for most of the first half.

Nigeria’s best chance fell to Oghenekaro Etebo in the second half but he scoffed his shot after a pass from Mikel.

A raft of changes by Siasia, who brought on Imho Ezekiel, Usman Muhammed and Stanley Amuzie, was not enough as los Cafeteros remained solid in the back.

Colombia cemented their win late on after Akpeyi brought down Harold Preciado inside the box. The goalkeeper was lucky to get a yellow card for the late challenge on forward.
