The Black Cats have been keen to strengthen their frontline having struggled for goals in the second half of last season, and now look to have sealed a key addition. But who could the new striker be? We take a look at 13 candidates who could fit the bill as Jack Ross closes in on a new face:
1. Will Keane
A free agent after leaving Hull City, the former Manchester United youngster has struggled for regular opportunities in recent years - and could now be looking for a new lease of life. Photo: Ian MacNicol
2. Dan Agyei
Another striker who could benefit from a loan move, Agyei is highly-regarded at Burnley and could be an asset in League One. Photo: Alex Livesey
3. Sam Baldock
Has been linked with Sunderland in the past and Charlton were believed to be keen this summer. Wages and a potential fee, though, could prove difficult to agree. Photo: Bryn Lennon
4. Leon Clarke
Transfer-listed by Sheffield United this summer, Clarke is a proven goalscorer in both League One and the Championship and could prove a fruitful addition. Whether he would drop to League One would have to be questioned. Photo: Aitor Alcalde
