Agent Walter Tamer says the Argentine would love to set up in Spain and with Barcelona showing of plenty of interest, there could be an 'extraordinary' deal done.
"Barcelona is the easiest deal to set up as Javier wants to go to Spain. He is tired of life in England," Tamer said.
"His wife has not been given a permanent visa. She has to go through an odyssey each time she wants to go.
"Liverpool refuse to sell, this can be overcome with an extraordinary offer."
