Real midfielder Gago hopes they can sign his countryman.
"Aguero is a player who could contribute a lot to any team in my opinion. It's not the right time to talk about it though. We're focused on the Copa America now," Gago said.
On those infamous comments about Real fans needing to accept Barcelona's superiority, Gago added: "My words were misinterpreted. What I said can be seen on video to clear up this misunderstanding."
