Chelsea boss Andre Villas-Boas insists he has no problem with his players keeping in touch with former Blues manager Jose Mourinho.
It was revealed this week that players regularly text the Real Madrid coach.
Villas-Boas said: "For sure, I have no problem with it."
He also reiterated he had no issue with Roman Abramovich's recent presence at the club's training ground or in the Stamford Bridge dressing room.
"I think the owner is entitled to do whatever he wants," he said.
