Barcelona are preparing to make a new proposal to Manchester City for Ferran Torres.
Barca directors Mateu Alemany and Ferran Reverter were in England last week for talks with City over Torres.
An opening offer of €50m was rejected by City, which rate the attacker closer to €80m.
As such, Barca hope to drive down City's cash price by including players in their next offer.
Sergino Dest, Sergi Roberto, Oscar Mingueza and Philippe Coutinho have all been mentioned as makeweights.
