Barcelona sports chief Andoni Zubizarreta insists their deal for Sporting Lisbon teenage pair Agostinho Cá and Edgar is rock solid.

Agostinho's agent has threatened legal action over the move, claiming an agreement was done without his knowledge.

But Zubi says: "The talks with the Portuguese are very advanced.

"We have a squad with many young players and we have to add to it so to keep up the level because some players have left."
