Leading the line of suitors for the Watford FC forward is Italian giants AS Roma who are keen to sharpen their attack with some fresh legs.
According to Calciomercato.com, the Giallorossi believe Ighalo has the quality that can improve their current goal-scoring problems and help Edin Dzeko feel more at ease.
Ighalo already has experience of playing in Italy, as the Watford player featured for Udinese and Cesena with a loan spell at Granada.
Udinese owners the Pozzo family also run Watford and Spanish side Granada, so regularly exchange players between these clubs.
The Nigerian international player has really found his form this term, scoring 13 goals in 18 Premier League games.
Also on the radar of Roma is Yannick Bolasie, the 26-year-old wide-left attack player has been at Crystal Palace since 2012 and found the net four times with one assist in 16 games this season.
