Portsmouth have had a second improved bid for Petrov rejected, as Celtic chairmen confirms no one has come close to meeting Celtic`s evaluation of the player.
Vital Pompey understands that Fulham is Petrov`s most likely destination although Quinn wants him to stay.
Quinn (Celtic chairmen) told the Sunday Times: 'I'm a bit old-fashioned. I think if you sign a contract you should stick to it.
'We had a long negotiation, and it wasn't a snap judgement by either party.
'Petrov committed himself to four more years at Celtic.
'I find it bizarre he's now taken the position he must leave.
'He's under contract to Celtic and we would only part with him if we had an offer that meets our valuation of the player.
'There's some way to go between the offers we've received and our valuation.
'We think he should buckle down and get on with it.'
