David Moyes is already planning for the January transfer window, according to reports today.
With Sunderland bottom of the Premier League table, the squad is already in need of reinforcements.
One area of particular concern is up front, with the reliance on Jermain Defoe evident, and Danish newspaper BT claim Sunderland scouts will watch Copenhagen striker Federico Santander in action against Club Brugge in the Champions League this week.
The Paraguayan international scored 14 times last season, and has notched three goals this campaign.
Swansea are also understood to be sending a scout to watch Santander this week, while Everton have been credited with an interest in the 25-year-old as well.
Elsewhere, Sunderland are interested in signing Pedro Carneiro, according to The Sun.
The 18-year-old Portuguese midfielder has been with Sunderland for a few days according to the paper, with the former Manchester City prospect reportedly trying to win a contract with the Black Cats.
Carneiro is a free agent and has also been linked to Portuguese giants Benfica.
Moyes, meanwhile, says Sunderland are paying the price for not completing their summer transfer business earlier.
