Sunderland and Swansea City will both reportedly send scouts to watch Copenhagen striker Federico Santander in next week's Champions League clash with Club Brugge.
Santander, 25, joined Copenhagen from Paraguayan side Guarani in the summer of 2015 and has scored 17 times in 41 league appearances for his current club.
According to BT Sport, both Sunderland and Swansea are interested in the forward and the two Premier League clubs will be represented in the stands when Copenhagen face Club Brugge on Tuesday night.
Santander, who has scored once in six appearances for Paraguay, signed a five-year contract with Copenhagen upon his arrival in June 2015.
