Babel admits he is frustrated by the club’s poor form.
Hoffenheim have only managed to get two wins in 15 games and suffered a 7-1 loss to Bayern Munich last weekend.
Babel told Sport1: “At the moment, we are playing football like we are confused.
“Personally, I have managed to improve since being at this club.
“But when you are playing for a team that has some problems, then it is tough to generally impress individually.
“Football is a fast moving business. It is possible that I may play for some other team in the future.
“I am hoping to see us achieve our goals here. If not, I have to very much consider my career.”
