Cristiano Ronaldo was denied by the woodwork as Portugal and Ivory Coast had to make do with a point apiece from a goalless draw in Port Elizabeth.

The Portuguese skipper, who has not scored an international goal in 16 months, rattled a post with a blistering early strike, but that was as close as his side came to snatching victory on a frustrating afternoon at the Nelson Mandela Bay Stadium.

Even Didier Drogba's arrival as a second-half substitute, to the delight of a crowd of 37,034, could not separate the sides as each attempted to gain the upper hand in Group G ahead of their respective encounters with Brazil.
