Kris Ajer has emerged as a transfer target for Bayer Leverkusen.

The German giants are keen to add the Celtic defender to their ranks and have already, as Herald and Times Sport understands, made tentative contact with the player's representatives.

It has been widely expected this summer that Norwegian Ajer would be willing to move on from Parkhead and there has been serious interest in the ace.

Newcastle are also considered to be very interested in Ajer and it is understood that newly promoted Norwich have the player on their radar as they plan an assault on the Premier League next season.

Ajer, 23, has made 53 appearances this campaign in all competitions including international fixtures and, despite the Hoops' poor season, has made a name for himself.

Leverkusen already have a relationship with Celtic having spent roughly £11.5million on former Parkhead right-back Jeremie Frimpong who cost the Glasgow giants just £300,000 from Manchester City.
