Substitute Seydou Doumbia rescued a point for 10-man Ivory Coast as the Elephants drew 1-1 with Guinea in their opening game at the Africa Cup of Nations in Malabo on Tuesday.

CSKA Moscow forward Doumbia finished low into the bottom left-hand corner of the net after linking up excellently with Wilfried Bony 18 minutes from the end of a dramatic Group D encounter between the west African neighbours in Equatorial Guinea's capital.

– Ivory Coast need to win African Cup, says Yaya Toure

Herve Renard's team, captained by African player of the year Yaya Toure, were widely considered favourites to get the better of the group outsiders but fell behind when Mohamed Yattara struck eight minutes before the interval.

And their hopes of taking anything from the game were seriously compromised when Gervinho was shown a straight red card early in the second half following a clash in the Guinea penalty area that left Naby Keita down requiring treatment.

They were lucky to remain on level terms in an opening half hour in which the Ivory Coast had the best of the chances, with Roma winger Gervinho breaking into the box and then seeing his shot turned against the bar by goalkeeper Naby Yattara after Bony failed with an initial effort.

Gervinho burst into the area again following a pass from Eric Bailly, only for Yattara to stop what was this time a weak attempt.

Instead it was Guinea, with Keita and Ibrahima Conte looking particularly enterprising in midfield, who got their noses in front on 37 minutes.

The Elephants' defence failed to deal with a hanging cross from Guinea's stand-in captain Ibrahima Traore, and Lyon striker Yattara lashed the ball high into the roof of the net much to the delight of the Syli Nationale's fans.

Renard was forced to look to his bench for inspiration and Doumbia took the place of Salomon Kalou as part of a double change on 65 minutes.

 The 27-year-old did not require long to make his mark, and both sides had to settle for a share of the spoils.
