Huddersfield Town striker Jordan Rhodes is on Sunderland's radar.
The Sunday Sun says Rhodes is being looked at, while Nikica Jelavic of Rangers has been linked in some quarters - although he has other suitors.
Bobby Zamora has been discussed but looks over-priced at £8m, and Sunderland will need to convince him about life up north.
Andrew Johnson, also of Fulham, is another option.
