Efe Ambrose has emerged as a transfer target for German Bundesliga outfit Bayer Leverkusen, who are reportedly ready to fork out 1.5 million pounds for the Nigeria defender.
Reports from Britain said the experienced Nigeria central defender could therefore be on his way out of Scottish champions Celtic on account of this interest from Germany.
The 27-year-old Ambrose joined Celtic in 2012 from Israeli club FC Ashdod for 800,000 pounds.
He has since established himself at the Glasgow club, but last season his first-team appearances were limited to 21 games as against 27 in the 2014/15 season and 38 in 2013/14 season.
New boss Brendan Rogers is already ringing the changes at the perennial Scottish champions.
