The left-back is not for sale, according to the Scot, who is desperate to retain his first-team stars as he bids to plot the Black Cats' survival
David Moyes has confirmed Sunderland have rejected an offer for Patrick van Aanholt and also dismissed reported interest in Adnan Januzaj as "pure speculation".
The bid for Van Aanholt is thought to have come from Crystal Palace, now managed by former Sunderland boss Sam Allardyce, but Moyes is not willing to sell.
"Yes (we have rejected a bid). He’s a really important player for us and he’s got an awful lot going for him," said Moyes at a news conference ahead of Saturday's home game with Stoke City.
