Arsenal are in contact with representatives of Bayer Leverkusen defender Jonahan Tah.
BILD says the Gunners are 'already getting serious' about bringing Tah to England this summer.
Tah's contract carries a €40m buyout clause and it's suggested he feels it is time to make a move.
However, Arsenal cannot wait too long to trigger the option as it expires before the summer's Euros.
Along with the Gunners, Atletico Madrid are also interested in the 24 year-old Tah.
