Swansea have confirmed their interest in signing Fabio Borini, but warned Sunderland there is no chance of Andre Ayew moving in the opposite direction.
The Black Cats have reportedly had a bid of £14million for Ayew, 26, rejected and they are thought to be considering Borini, 24, in any fresh offer.
But Swansea coach Alan Curtis says that although his club are keen on Borini, there is no chance of a swap deal involving Ayew.
“Fabio would be one of a number of players whose name has been mentioned,” said Curtis at a press conference on Friday.
“But the talk of Andre going there as some sort of part of the deal is wide of the mark.
“I spoke to the chairman [Huw Jenkins] just to clarify the situation and he assures me that there is no way that Andre will be allowed to leave during this window.
“On that basis, whether Fabio was part of a deal involving Andre I don’t know, but certainly Andre is out of the deal.”
Borini scored six goals in nine Championship appearances for Swansea during his loan spell from Chelsea in 2011, helping them win promotion to the Premier League.
The Italian has since played for Parma, Roma and Liverpool, leaving the Anfield club to join Sunderland permanently last summer.
Ghana captain Ayew joined Swansea on a free transfer in June 2015 after his contract at Marseille had expired.
He has scored seven goals in 22 appearances for the Swans, including a goal in the 4-2 loss to Sunderland at the Liberty Stadium earlier in January.
