Leicester City and West Ham United are among the clubs interested in signing the 27-year-old winger.
“We either have to do a contract here, or my gut feeling, is that if a contract is not signed at Reading, then something will happen somewhere else,” McDermott told the Reading Post.
“There will be interest from other parties, I know that.
“We’ve had interest and we’ve had a bid. We turned it down, but that’s all I will say.”
