He told TyC Sports: “River are a club that gave me everything, from letting me develop to Real Madrid buying me, but right now I don’t know what’s going to happen. My head is here [in Turin].
“[Marcelo] Gallardo’s team are very exciting, they have quality, strength, everything.
“The truth that you watch them and their number nine gets many chances. Clearly someone who played for River before will watch that team, see themselves there and say, ‘how nice’.
“Gallardo has caught everyone’s eyes and he’s earned it. I’d think about going back to River to retire.”
