Mainz goalkeeper Loris Karius is a target for Arsenal.

The Mirror says the shot-stopper, 21, is the youngest keeper in the Bundesliga with Mainz.

Karius, who used to be part of Manchester City's academy set-up, is now on the Gunners' radar.

Arsenal are prepared to wait until the summer but rival suitors are looking to snap Karius up on the cheap this month, which may force Arsene Wenger's hand.
