The hitman has returned to Argentina to spend time with his daughters, and attended a charity auction where one of the prizes was a ticket to watch him play.
However, he told the Daily Mail: "Yes, there is a prize to come over to Manchester to watch a game but that doesn't mean anything. It could still change.
"Maybe the trip will end up being to somewhere else in Europe or to Argentina. I don't know.
"But for now I've got a contract with Manchester City, so that's where the trip is to."
