However, Chinese club Changchun Yatai, want to recoup the £20m they spent to sign him from Watford in January 2017, if they are to sell.
Shortly after joining Changchun Yatai, Ighalo claimed his preference was to remain in England.
He said at the time Crystal Palace and West Brom were interested, but the figure Watford were asking for was too high.
The Nigerian is expected to fly into the UK this week to discuss his future.
Ighalo has scored 36 goals in 55 games for Chanchung Yatai.
