Aaron Hunt is concerned that Werder Bremen will become embroiled in a relegation battle if they fail to strengthen before next season.
Werder finished 14th last term, just three points above a relegation play-off spot, and Hunt fears things could get even worse next time around.
The Germany international’s own future remains up in the air, with a contract yet to be agreed between the midfielder and the Bundesliga outfit.
And the 26-year-old admitted that the loss of Chelsea loanee Kevin De Bruyne and the departure Sokratis Papastathopoulos to Borussia Dortmund could jeopardise the club’s top-flight status.
It is an issue that could force him to look elsewhere.
“I have said I want to wait on the progress the club is going to make,” Hunt told Kreiszeitung Skye.
“Just because I have the ambition to get back to regular football in a European club competition.
“It should not be our ambition to drag ourselves about in those lower zones of the league table. We need cover for Kevin De Bruyne and Sokratis Papastathopoulos.”
