Burnley have made an £8m bid to Swansea for midfielder Sam Clucas, according to Sky sources.
Swansea manager Graham Potter confirmed an offer had been made for the player at a press conference on Thursday afternoon.
Burnley boss Sean Dyche is a long-term admirer of Clucas, having lost out on the 27-year-old when he joined Swansea from Hull City last summer.
Clucas made 29 Premier League appearances last season as Swansea succumbed to relegation after seven years in the top flight.
Sky sources understand that Burnley and Swansea have held talks but negotiations still have some way to go before a deal can be reached.
