Robert expects an agreement before the end of this season.
He told Sport: "The president [Josep Maria Bartomeu] has already said. This year there are a number of situations we need to solve. As was the case with Rafinha, Busquets, Neymar and Mascherano, people said we wouldn't reach an agreement, but in the end there were no problems. "There's no rush. This season we will reach an agreement. Like we did with Rafinha, Mascherano, Busi and Neymar."
