Blackburn have rejected two official bids from Chelsea for winger Damien Duff, BBC Radio Lancashire reports.
Rovers chief executive John Williams is refusing to disclose the size of the offers.
However, he confirmed Duff has an escape clause in his contract which allows him to talk to other clubs if they offer a certain figure.
BBC Sport understands that sum is £17m.
Williams admitted the bids were "close" to that figure and that could prompt Chelsea to return with a new bid. |
