Speculation concerning the future of French starlet Rabiot has been rife for many months now, with the player seemingly having become understandably frustrated over a lack of regular first-team opportunities received amid particularly fierce competition for places at the Parc des Princes.
London rivals Arsenal and Chelsea - along with Serie A title hopefuls AS Roma - have been most frequently linked with the talented 19-year-old over recent months, with PSG boss Blanc giving each of those clubs new cause for optimism that a deal could be struck in the new year.
"If we sell Rabiot, it will be in January," the former Manchester United defender was quoted by The Daily Express.
Blanc also warned that any potential deal transfer involving Rabiot will have to be conducted in the correct manner, despite PSG being placed under increased pressure to sell with his current contract due to expire in 2015.
"But there will have to be an agreement with Paris Saint-Germain," he added. "Our code of conduct preludes a free transfer.”
Rabiot - an U21 international who joined the reigning Ligue 1 champions back in 2010 - is yet to appear for PSG this season but scored two goals in 25 league appearances during the last campaign as Blanc's side collected their second consecutive title with a nine-point buffer over fellow moneybags AS Monaco.
If indeed Arsenal or Chelsea do intend to revisit their long-standing interest in Rabiot when the market re-opens for business in three-and-a-half months time, then it does not appear likely that they will have to break the bank in order to bring him to the Premier League.
Reports have estimated that his price tag stands at around the £9.5 million mark - a dramatic reduction from the £24 million that PSG were previously demanding - although his salary demands are rumoured to be somewhere in the region of £2.5 million-per-year.
And given that Rabiot himself is believed to favour a switch to Serie A, Jose Mourinho and Arsene Wenger may have their work cut out to convince him over a potential move to England even if those aforementioned wage requirements are met in full.
