Swansea City interim manager Alan Curtis has claimed that the club will not "entertain" bids for Andre Ayew.
The 26-year-old Frenchman, who joined the Welsh club from Marseille last summer, is said to have attracted interest from fellow struggling Premier League side Sunderland.
It has been reported that the Swans have rejected a £12m offer from the Black Cats, and Curtis has insisted that the forward is not for sale.
"There was talk of him going to Sunderland or them making a bid, but we wouldn't even entertain that as far as I am concerned," The Mirror quotes Curtis as saying.
"He is one of a number of big players for us and we don't want to lose anybody during the window. We want to bring people in and we will get somebody in. But if we don't it's important no one else goes out through the door."
Ayew has scored seven goals in 22 appearances so far this season.
