Behrami played a key role in Watford's successful battle against relegation last season but now the 32-year-old has expressed his desire to leave Vicarage Road this summer.
The former Napoli star has admitted that he has already asked permission from Watford to leave and that he is currently in discussions with Swiss Super League side Sion over a possible move in the coming weeks.
"I have told Watford that I want to move, and they will decide what happens. But I will accept whichever decision they take, as I get on very well with them.
"I now hope to have four weeks off. I need this time for the sake of my mind and my body, as this last season hasn't been the easiest. The next contract I sign will probably be my last, so I have to give it serious thought."
