Ivory Coast coach Sven-Goran Eriksson is sweating on the fitness of striker Didier Drogba and Arthur Boka is a doubt with a thigh problem as the Elephants prepare to open their World Cup campaign against Portugal.

Eriksson is quietly confident Drogba will play in Tuesday's opener if FIFA allow the Chelsea forward to wear a lightweight cast on a broken elbow suffered in a friendly match against Japan.

Meanwhile, Portugal winger Simao Sabrosa claims he is fully fit - but still not guaranteed to start, despite Nani's withdrawal from the tournament.
