The France international was believed to be close to joining AC Milan earlier in the off-season, but the move eventually fell through, as Milan refused to meet Montpellier’s valuation of the defender.
Fresh reports have suggested Milan could make another move for Yanga-Mbiwa in January, but Nicollin has claimed the centre-back is going nowhere.
“Is there any possibility that Yanga-Mbiwa will leave in January? Absolutely not,” Nicollin told calciomercato.com.
“We’re working on extending Yanga-Mbiwa’s contract. In any case, the only thing that’s certain at the moment is that Yanga-Mbiwa won’t leave in January.
“Are Juventus and Barcelona are also interested in Yanga-Mbiwa? To be honest, nobody has asked us about him. I don’t know if any clubs have been in contact with Yanga-Mbiwa’s agent, and I honestly don’t care.”
Yanga-Mbiwa’s contract with Montpellier is due to expire at the end of the season.
