Celtic are rumoured to be interested in signing the Scotland international, but Levein underlined his desire to keep hold of Robson:
"We've not had an offer for Barry and I hope we don't get one. We don't want to sell him.
"We're looking to stay in the top six and get into at least one cup final and he's an important part of what we're doing here.
"People are only worth what others are willing to pay for them. When you see what others are going for and compare them to someone of Barry's ability, then I'd say he's worth £1.5m or even £2m.
"He's under contract for three more years and I have no indication that he wants to leave."
