It is understood the Reds are keen to land the talented Frenchman on a three-month loan deal with a view to a permanent move in January.
Wanderers rejected improved offers from Forest leading up to the close of the summer transfer window, with the most lucrative believed to have been in the region of £3.5million.
The Black Country club are keen to keep hold of Sako, who already has five goals this season, as they aim to secure immediate promotion from Sky Bet League One, with their valuation of the 25-year-old standing at £4million.
And in response to Forest's latest interest in their prized asset, Wolves' stance has not budged.
An official statement released through social media channels read: "Wolves are aware of the loan/transfer speculation surrounding Nottingham Forest and Bakary Sako.
"Forest have renewed their interest, but the situation remains unchanged.
"Bakary is an important player and his value reflects that. Wolves are not encouraging the interest and there is no certainty of a deal."
The transfer window shut ages ago. Sako was deemed important enough to Wolves for them to turn down offers from Nottingham Forest at that time and, in any case, Wolves made it clear that they weren't going to consider selling a player of such importance when the chance to replace him was almost non-existent. Nothing in that has changed. However, we now see a blatant bending of the transfer rules taking place as teams like Forest (and Wolves earlier this week for that matter) seek to acquire players on loan as a precursor to buying in the next transfer window. This completely defeats the reasons for having these set windows of time and flaunts the rules and principles behind allowing clubs to make emergency loan deals once the transfer windows have closed. Either these sort of deals should be stopped and clubs fined for trying to make them or the transfer windows should go. Personally I think the windows should stay and clubs be made to adhere to them thus creating stability in those clubs unlucky enough to be targetted to sell their best players. Loan bids should only be for those players which owner clubs have listed as available for the purpose. In this case, if Forest want a Wolves player that badly, they could try for Jamie Ohara who is apparently persona non gratis at the club or go for Hunt who is a completely free agent.- andy
