Aberdeen chairman Dave Cormack has issued a warning to clubs pursuing the transfer of Scott McKenna, insisting the club will be letting him go on their terms only.
The Reds, however, were not the only club expressing an interest in the centre-back over the summer.
It is believed that Forest and Queens Park Rangers had transfer offers rejected within the region of £3m, with Premier League new boys Aston Villa also having a much bigger offer turned down – said to be in the region of £6.5million.
Stoke, Swansea, Hull and Celtic are also said to have been interested in the 23-year-old, although no formal bids were reported from these clubs.
McKenna is expected to have a market value of somewhere between £6m-£10m and Cormack says the club will not be forced into selling any of their assets.
Speaking to the Press and Journal, he said: “We are under no pressure to sell anyone and we’ll only do that on our terms.
“Obviously, if there is a substantial return on a player and it makes sense for us then we would consider it.
Cormack was keen to stress the importance of giving the Aberdeen boss Derek McInnes the best chance of finishing strongly in the league this season.
He added: “We would only consider it after speaking to Derek and it makes sense for him, with his ins and outs for the window.
“We are all human beings, players have contracts and like in the case of Scott McKenna there has been interest but not to the level we wanted.”
Forest will be looking to improve on a shaky couple of weeks in the league as the Reds were taken apart by Sheffield Wednesday in a 4-0 hammering at the weekend.
