The Mirror have revealed that Arsenal have inquired about the availability of Mats Hummels.
The Gunners are planning to battle Manchester United for the signing of the German youngster.
United boss Louis van Gaal has made the Borussia Dortmund star his first priority, but the club is determined to keep him. The Red Devils boss is insistent that he could get his hands on him for around £30million.
However, the Gunners are now determined to challenge Manchester United for the player.
Also, Arsene Wenger still has the financial power to sign the player despite the signing of Alexis Sanchez, David Ospina, Calum Chambers and Mathieu Debuchy.
Van Gall, on the other hand, does not have very experienced central defenders available and he is planning to bring on new names at the back.
However, Arsenal have Champions League football, which Manchester United does not and they could challenge United for the star.
