West Bromwich Albion have rejected a bid, thought to be in the region of £1m, from Derby County for midfielder George Thorne.
The 21-year-old spent four months on loan with the Rams last season and they are keen to make the deal permanent.
Baggies technical director Terry Burton told the club website: "We have no intention of selling George."
Meanwhile Derby have sealed the free transfer signing of ex-Arsenal and Sevilla midfielder Alban Bunjaku, 20.
He has signed a two-year contract.
Head of football operations Chris Evans told the club website: "Following a successful trial, we are delighted to welcome Alban on board.
"He fits the criteria for the type of player we want to bring in for the development group."
Thorne played a pivotal role in helping Derby finish third in the Championship and reach the play-off final last season.
Burton added: "We have told Derby he is not for sale and that is the end of the matter as far as we're concerned."
