Denis Zakaria is unsure about renewing his contract with Borussia Monchengladbach.

The midfielder has been linked with Manchester City as a potential successor for Fernandinho, while he is also interesting Roma.

Roma are expected to make a move for the Switzerland international in January.

He said, "If Mourinho called me? I don't want to go into details, with Roma there was nothing specific.

"I don't know if I will extend with Borussia or if I will leave."
