West Bromwich Albion have stressed Graham Dorrans is not for sale after rejecting a second bid from West Ham United.
Skysports.com revealed earlier on Thursday that the Hammers had launched a fresh attempt to persuade West Brom to sell the Scotland international.
An offer of £4million was previously rejected at the end of April and West Ham returned with an increased bid of £4.5million for the midfielder.
However, that offer has again been given short shrift by the newly-promoted Baggies, who are determined to keep Dorrans at The Hawthorns.
Sporting and technical director Dan Ashworth told the club's official website: "As I have stressed several times since we achieved promotion, our aim is to retain our core players and try to strengthen our squad around them.
"I want to make it clear again that Graham Dorrans is not for sale.
"Graham signed a new contract until June 2014 in January and he remains a key member of our squad."
Dorrans, who joined from Livingston in 2008, scored 18 goals for West Brom last term and was named in the PFA Championship Team of the Year.
