Niclas Fullkrug's agent has admitted his move to West Ham has not worked out.
The German striker has scored just three goals in 27 appearances since arriving from Borussia Dortmund in the summer of 2024.

Fullkrug penned a four-year deal at the London Stadium when making his £27million move to the Premier League.
His time in England has since been littered with injury woes, though, with the 32-year-old missing 31 matches for club and country.
He also launched an explosive rant aimed at his own teammates back in April following a draw with relegated Southampton.
Fullkrug's X-rated outburst saw him accuse the squad of having a 'mindset problem'.

The forward's agent has now suggested the time has come for Fullkrug to seek a move away from the Hammers.
Appearing on the TOMorrow Business Podcast, Thorsten Wirth explained: "Looking back, we have to say the transfer didn’t work out. There’s no point in sugar-coating it."
When asked if his client should leave English football, the agent added: "This always has to happen in cooperation with the club, but I believe it can make sense to change something there."
The Germany international still has over two years left on his Hammers contract, which expires in the summer of 2028.
Fullkrug is once again sidelined through injury, having now missed his side's last three matches.
The latest of those saw West Ham come from behind to beat Newcastle on Sunday.

Nuno Espirito Santo's first win as manager came courtesy of goals from Lucas Paqueta and Tomas Soucek either side of a Sven Botman own goal.
Wirth believes that injuries are to blame for Fullkrug's woes in claret and blue, the agent saying the player's time at West Ham has been littered with 'negative momentum'.
His current muscle issue follows lay-offs last term prompted by hamstring and Achilles injuries.
Meanwhile, Fullkrug is not expected to return to action until after the upcoming international break.
The Hammers' first match after their two-week lay-off will see them visit Bournemouth on November 22.
Discussing Fullkrug's fitness woes, Wirth continued: "Time and again, at a point where you said, 'Now he’s coming, now he’ll show England that it wasn’t just a good European Championship and then nothing more will come of it', another injury came along, and that’s a shame.

"He had a bit of a negative momentum and also some bad luck."
An exit for Fullkrug may not be sanctioned until a new player is brought in, though.
His current absence has left Callum Wilson as Nuno's only recognised senior striker.
The former England international has been supported in carrying the goalscoring burden by 20-year-old academy product Callum Marshall.

However, the duo have just one goal between them across a combined ten appearances this term.
Despite that, the Hammers were able to secure a first home win since February on Sunday to move within three points of safety.
