Besiktas are interested in Manchester United midfielder Shinji Kagawa.
The Japan international is expected to be sold by United manager David Moyes in the summer after the arrival of Juan Mata from Chelsea last month.
A return to Borussia Dortmund has been mooted, though Kagawa's availability has also alerted Besiktas.
Turkish sources say Besiktas are wiling to offer a contract package worth more than the midfielder is on with United - and will be far greater than what BVB can afford.
