West Brom have been linked with Derry City winger Pat McCourt.
"The offer had been rejected because we feel it is derisory - it's insulting to the club and the League of Ireland in general," said Derry City chairman Pat McDaid.
A second Premier League side are among a host of clubs interested in McCourt.
McCourt added: "We have another Premiership club, a couple of Championship teams and a couple of sides from the SPL in Scotland interested in Paddy.
"We have been speaking with the clubs over the last couple of weeks."
