Darmstadt striker Antonio-Mirko Colak is being watched by Arsenal.
Colak is on-loan at Darmstadt from Hoffenheim and scored twice in last weekend's 2-2 draw with Werder Bremen.
The Gunners are watching the Croatia U20 international, 23, leading up to the January market.
Born and raised in Germany, Colak has been capped at U20 and youth level by Croatia.
Colak stands at 6ft 2in and is being linked with Arsenal as potential cover for Olivier Giroud.
