Preston North End have issued a bullish transfer statement amid interest in their top stars from Celtic and Rangers.
The Championship side have attacked several unnamed clubs allegedly conducting their business "through the press and social media".
Record Sport understands Rangers are interested in midfielder Daniel Johnson while Celtic have placed defender Ben Davies under surveillance.
Davies is also believed to be on Bournemouth 's radar.
Reports in England have insisted an Ibrox deal for Johnson is close but Preston are adamant no satisfactory offers have been made for any of their players.
Owner's representative Peter Ridsdale went on the attack on Monday as he shot down social media rumblings.
He wrote: "Ordinarily we don’t comment on transfer speculation, however, the last few days have been frustrating as it would appear that a number of clubs are attempting to do their bidding through the press and social media.
"Some of the so called ‘informed’ comments have claimed that transfer fees have been agreed between us and at least one other club for named players.
"At the time of writing this statement no bids for any of our players have been agreed. Any approaches that have been made have been underwhelming in both quantum and payment timescales.
"We have always accepted that buying and selling players is a normal part of our business, but at the right price.
"Some of the so called ‘informed’ comments on social media are not only unhelpful, but frankly not true.
"We attempt to conduct our transfer dealings club to club and only announce a deal once all parties have agreed.
"We have made bids for a number of players this summer but as deals were not finalised we have refrained from confirming the identity of potential targets. This will remain to be our approach.
"If and when there is anything definitive to say for either incomings or sales we will make a factual statement at that time."
