Nigerian international Chinedu Obasi is attracting interest from the Championship after his unsuccessful trial at Sunderland
Obasi spent several days training with Sunderland at the Academy of Light last week, before Sam Allardyce opted against pursuing his interest in the striker.
But the 29-year-old - a free agent after being released by German side Schalke in the summer - is a wanted man.
"Obasi had a relatively successful trial but for obvious reasons the club wants someone who can make an immediate impact," a source close to the player told the BBC.
"There are some interested clubs from the English Championship because he has a lovely CV for a free player."
Allardyce is interested in any players available on a Bosman deal who can strengthen Sunderland's attacking options.
But as he told the Echo today, he will only make signings who can make an immediate impact, with the January transfer window just two months away.
Meanwhile, former Sunderland midfielder Dwight Yorke says Sir Alex Ferguson has backed his bid to take charge at managerless Aston Villa.
"Sir Alex has spoken to me and given me his backing, he believes I can do it," Yorke told The Sun.
