Torres knows Cesc is wanted by Barca for the summer market.
He told Sport: "I do not know. It is a question for (Pep) Guardiola. I do not follow the Spanish Liga much, but I think Barca is a tough team to improve. If Cesc goes there, who does he replace?"
Torres added: "He would be a great signing, of course. Cesc is more valued and respected in England than in Spain, where he has never played."
