Robben has enjoyed a good spell with Bayern but has had problems off the field, notably a spat with Franck Ribery in April.
“Clearly, I feel at home in Bayern … but so many things play a role when you extend. That’s why you have to think very carefully before you make a decision,” he told Kicker.
“There are other possibilities, but that’s normal when you play for a top club. And people know what I can do.”
