Former Chelsea boss Carlo Ancelotti claimed this week that Torres's form was suffering under Drogba's presence, and he said that the Blues would have to sell the Ivory Coast star to get the best out of the Spaniard.
"I respect Carlo's opinion but, for me, it is not the case," Villas-Boas said. "It has not even crossed my mind to sell Didier in this transfer window. I still rely on him for what he represents as a player and icon.
"We are speaking about two of the best players in the world and it would be unfair to conclude that Didier is inflicting his personality on Fernando. If that was the case it would be a mental weakness or a mental block.
"That is not the situation here."
Ancelotti signed Torres from Liverpool this time last year for a record-breaking £50m.
