German side RB Leipzig are considering a move for Newcastle United target Kristoffer Ajer.
But the Norwegian international is believed to be second choice for the Bundesliga side, and they will only follow up their interest if they don't sign Wolfsburg's Maxence Lacroix.
Reports this weekend say Ajer is now on Leipzig's radar after a series of impressive performances for Celtic, with Newcastle United also keen on the 23-year-old.

Magpies scouts have followed the defender's progress and, with one year remaining on his contract at Celtic Park, he is expected to move on this summer.
Bayer Leverkusen are another side with interest in Ajer, but Newcastle are hoping to strike a deal of around £6-8million for the highly-rated Norway international.
Ajer is predominantly a centre-half, but has played at right-back for Celtic and his versatility is a factor which is attracting clubs this summer.
Speaking about his future earlier this summer, Ajer said: “With one year left of my contract, that would be the best solution for me and my club. Something is going to happen this summer.
"There are of course many rumours. Right now it's just rumours.
"I have one year left on my contract with Celtic and I relate to it, but something will probably happen this summer.
"I have one year left and will be loyal to the club.
"For both me and Celtic to get the best possible starting point, it probably makes sense that it happens this year.
"I have brought with me experience from almost 180 games for a top club like Celtic."
