Marko Arnautovic has hinted he could leave West Ham United to play with "the best players".
The Hammers striker has bagged five goals in 10 appearances for Manuel Pellegrini's side this season.
"I'm 29, so that's the best age," the West Ham star told Kurier.
"It's clear that I want to compete with the best players. But in this affair I totally trust my brother."
Arnautovic's brother Danijel, who is also his agent, says the 29-year-old could leave the London Stadium in the near future.
"He's a big part of West Ham's team but I think it's possible to tease out more of him. For that to happen, he has to play for a top team," he said.
"Marko is ready for the next step. A player like him should not play against relegation. He should play for the international spots.
"Marko is really enjoying playing for West Ham. He loves that club and the fans. But there is still that feeling, that this cannot be the end. And everybody should understand that."
Arnautovic was linked with Manchester United in the summer, despite his chequered past with Jose Mourinho.
And when pressed on whether his brother could leave West Ham in the near future, Danijel. added: "That's possible. It was already very, very close this last summer."
