Newcastle United are facing competition as they look to sign Celtic defender Kristoffer Ajer.
The Norway centre-back has admitted in a recent interview that he may move on from the Scottish giants this summer.
According to Kicker in Germany, Bayer Leverkusen are very keen to sign Ajer.
The Magpies are very keen on Ajer, according to the source, while newly promoted Premier League side Norwich City are also in the mix.
Prospective suitors will not get a chance to see Ajer at this summer's Euro 2020, after Norway failed to qualify for the tournament.
