Bhoys make £2.5m bid for Besiktas defender
Celtic have made a €3 million (£2.5m) bid for Besiktas defender Dusko Tosic, reports Turkish outlet Aksam.
According to the report, the Scottish champions have made an offer for the 32-year-old centre-back, but Besiktas are holding out for €4m.
Tosic, who is a Serbia international, counts Werder Bremen among his former clubs and played in England for Queens Park Rangers in 2010.
Celtic are said to be on the look-out for defensive reinforcements this January and are already short in the department, having let Erik Sviatchenko join Midtjylland on loan.
