The Nicoilas Todt managed driver jumps to the top of the favourites list.
Dec.13 (GMM) Jules Bianchi has leapt into pole position to join Paul di Resta at Force India next year.
Earlier, it was expected the Silverstone based team's former race driver Adrian Sutil was the favourite to replace the Sauber-bound Nico Hulkenberg in 2013.
"The announcement is expected before Christmas," said correspondent Heikki Kulta.
Kulta added that Force India's reportedly likely switch from Mercedes to Ferrari engine power for the 2014 V6 regulations was "a decisive factor" in Bianchi's favour.
