Virgil van Dijk claims he knows nothing of interest from English clubs and is keen to prove himself in the Champions League with Celtic.
Montpellier coach Jean Fernandez has resigned after overseeing a run of seven Ligue 1 games without victory that has left the 2012 champions flirting with relegation.
Wednesday night's 2-0 defeat to Lorient at the Stade de la Mosson was a fourth reverse in seven matches while Montpellier have won only twice this season under the supervision of 59-year-old Fernandez.
The former Marseille and Auxerre coach replaced Lille-bound Rene Girard in the summer and delivered a 2-1 home win over Sochaux in his third league game in charge. MHSC beat Lyon 5-1 on October 6 but have not won since.
A Tweet from Fernandez on the club's official Twitter account read: "In the interests of the club and the team I have decided to stop."
Montpellier owner Laurent Nicollin has entrusted long-serving coach Pascal Baills with the first team while he "studies options" for Fernandez's successor.
