River Plate coach Marcelo Gallardo confirms Manchester City have agreed a deal for Julian Alvarez.
City will pay £17m to sign the Argentina striker and it has already been agreed that he will stay at River Plate on loan until the summer.
Gallardo told ESPN in Argentina: "Yes, in theory until June and there's also a chance he might stay until December, but that's for another day.
"As for having him here with us and the chance to finish the year here, River Plate have negotiated very well.
"A huge club came in for him. We're not talking about a second-rate club, but one of the biggest in the world with financial power and, at the moment, that's enabled us to hold on to the player because there's no place for him [at Manchester City] or they don't need him right now.
"We'll see if he stays here in June or not, but it keeps that option open. It would've been very difficult for us to go out and try to sign a player with his attributes in this transfer window if he left now."
