The agent of West Ham United forward Marko Arnautovic has suggested that his client could leave the club in January.

Arnautovic has scored five goals in 10 Premier League appearances for the Hammers so far this season but has been linked with a move to a top-six club, with Manchester United currently the favourites for his signature.

The 29-year-old's agent and brother Danijel Arnautovic insists that Marko is enjoying life at the London Stadium, but revealed that he wants to move on in order to fulfil his ambitions of playing in Europe again.

"[A January exit] is possible. It was already very, very close this last summer. He's already playing in the Premier League and that's where the best players are. But for a player like Marko this cannot be the end," Danijel told Austrian newspaper Kurier.

"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. 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 joined West Ham from Stoke City for a then club-record fee of £20m in 2017.
