Millwall striker Lee Gregory is wanted by Sunderland and Sheffield Wednesday.
The 29-year-old has one year left on contract at The Den and the Championship rivals are keen to strengthen their options in the summer.
For Sunderland, who faced Millwall on Saturday, much depends on whether they can avoid a successive relegation but Wednesday are keen to sign the Sheffield-born forward who has scored eight goals this season and 62 since signing for Millwall in 2014.
The former electrician, who joined from non-league Halifax Town, has attracted plenty of interest over the past year and Wednesday expect competition should Millwall listen to offers.
