Manuel Pellegrini has suggested that Sergio Aguero could stay with Manchester City after his five-year contract expires with the club.
Aguero, 27, told radio station Independiente en la Uno that he intends to see out his current deal, which he signed in 2014, before rejoining his former club Independiente in Argentina after the 2018 World Cup.
However, Pellegrini believes the striker could yet change his mind and remain at the Etihad Stadium for longer.
"It's a decision that Sergio knows why he wants to do it," Pellegrini said. "It's difficult to talk about what will happen in two or three years, because players change their minds.
"Maybe he will be happy to return to Argentina, but Kun has a lot more years here in Europe."
Aguero has 10 goals in his last 10 games ahead of Saturday's lunchtime game at Norwich City, which could see City reduce the gap on Premier League leaders Leicester City to seven points.
City have scored 16 goals in their last five games at Carrow Road, including a 3-0 victory in the FA Cup third-round in January, and Pellegrini is hoping for more of the same.
He added: "Every game is different. The cup we played there, we played very well.
"I'm focused on trying to continue being a solid, consistent team without conceding goals, and trying to be return to be a scoring team like we did in the last game against Aston Villa."
The Chilean added that it was crucial that City put their title rivals under pressure going into the international break with a win at Norwich followed by a victory in next week's Manchester derby.
"It's very important because if we win the next two games in Premier League the pressure will be more on the other teams," Pellegrini added. "But we know that we must win if we want to continue being involved in the title to the very end.
"If we can get to the quarterfinals of the Champions League for the first time of course that will be another important achievement.
"I hope that we will do that, but we must start by thinking just about Norwich."
