Burnley boss Sean Dyche reportedly maintains an interest in signing Pumas striker Nicolas Castillo.
During the closing days of the transfer window, Dyche broke the club's transfer record to sign Chris Wood from Leeds United, but it appears that the Clarets were also keen on another frontman.
According to CDF, Burnley were in contention to bring Castillo to the Premier League after the Chilean netted eight times in 11 outings for Pumas.
The move was allegedly unsuccessful due to visa issues, but it has been suggested that Dyche is considering returning for the 24-year-old at the start of 2018.
Castillo - who has won nine caps for the South American nation - has previously had a spell in Europe with Club Brugge, netting 10 goals in 30 league appearances.
