Villas-Boas endured a turbulent time during his short stay at Stamford Bridge and he has hinted that he did not part on the best of terms with the Russian billionaire.
Villas-Boas told The Sun: "Have I spoken to him since I left? No.
"Will I speak to him or shake his hand at the match? No. It is highly unlikely that he will be allowed into the dressing room or the tunnel."
Tottenham face Chelsea on Saturday as Villas-Boas comes up against his former side for the first time since he was sacked in March.
