Arsenal are preparing to "test the waters" in January with an offer for a rising star in the Bundesliga, as Mikel Arteta looks to bolster his squad.
Riccardo Calafiori and Mikel Merino arrived in the summer on permanent transfers, while Raheem Sterling and Neto are loan deals Arsenal completed. So far, though, those signings have failed to bring the Gunners closer to that elusive Premier League title, with Arteta's side now seven points behind leaders Liverpool after just 10 games.
