Hertha Berlin are ready to test the resolve of Arsenal over Matteo Guendouzi.

The midfielder is impressing on loan at Hertha Berlin, with the Bundesliga side having lost just once in seven games since he broke into the first team last month.

And Hertha want to sign the France under-21 international on a permanent deal, says Der Tagesspiegel.

With Guendouzi's Arsenal contract set to expire in 2022, next summer could be the last chance for the Gunners to recoup a transfer fee for the France under-21 international.

So Hertha could move when the transfer window opens next month in order to beat any competition for the 21-year-old's signature.
