Eto'o will join Cameroon just a week before the start of the Nations Cup

The administrative director of the Cameroon football federation, Albert Njuigol, told BBC Sport that coach Otto Pfister has agreed that Barcelona can keep Eto'o until the weekend.

Cameroon had been insisting that Eto'o should join them on Monday.

But Barcelona wanted him to play two more games in Spain.

Barcelona coach coach Frank Rijkaard said on Tuesday that they have the go-ahead to keep the player.

"We have written permission from the Cameroon Federation," Rijkaard told a news conference.

"The important thing for Samuel is to play and the federation and their coach have seen that that is best for them and for us."

Barcelona have included Eto'o in their squad to face Sevilla in the first leg of their King's Cup last-16 tie on Wednesday.

They also expect to field him at home to Real Murcia in the Primera Liga on Saturday before he joins Cameroon.

Cameroon are holding a a training camp in Burkina Faso.

The rules of football's world governing body Fifa state that clubs must release players two weeks before the start of the tournament.

But a player's club and national team can come to an agreement to delay the release of the player.
