Carlos Queiroz insists he will not change his game-plan for Portugal's World Cup opener despite the likely absence of Ivory Coast captain Didier Drogba.

The forward underwent an operation on Friday for a fractured arm and, although the Ivory Coast are refusing to rule him out of the tournament, he is almost certain to miss the clash with Portugal in 10 days' time.

However, Queiroz said: "We are not going to change anything in our plans. When great players are out of a World Cup - as also happened with my great friend Rio Ferdinand - it's always a shame, a blow for the spectacle."
