The future if Sead Kolasinac at Arsenal remains clouded.

The left-back had been linked with a return to former club Schalke over the summer, but in the end remained an Arsenal player when the market shut on October 5.

However, BILD says Bayer Leverkusen are now seeking to bring Kolasinac back to Germany in January.

Contracted to Arsenal until 2022, it's understood Kolasinac is eager to leave London and would welcome a move to Bayer.

Roma and Napoli are also monitoring developments.
