The former Porto manager endured a 3-1 defeat at the hands of the Premier League champions last weekend.
The Portguese boss said that he was "surprised" at the reaction from pundits, who described Chelsea's tactics as "naive and stupid".
"I am surprised that people take the view to criticise us for being naive and stupid at Old Trafford," Villas-Boas said. "What we did was defend the essence of British football and football well played.
"It was an entertaining game for the world. Pity we didn't come away with the three points but I think we were superior during the 90 minutes.”
Meanwhile, the Blues take on newly-promoted side Swansea at Stamford Bridge this weekend.
