Schalke 04 are keeping tabs on Arsenal winger Serge Gnabry, according to SkySports HQ, and their sporting director Christian Heidl has reportedly revealed: "All German clubs except Bayern Munich are looking at him".
It is understood Arsene Wenger would only consider to let the 21-year-old leave on a season-long loan as he considers him a good profile to shine at the Emirates in the next seasons.
