But he returned to lead the side against Bolton - and scored his 150th Premier League goal.
"There have been certain issues," Lampard said. "Certain players, we don't like not to play.
"But it's never a case of players throwing their toys out of the pram to the detriment of the club.
"The only way we can push on from now and secure Champions League football next year, potentially move through in the FA Cup and the Champions League this year, is to be positive.
Villas-Boas relieved after victory
"It's in the club's interest. It's not about any one individual here and negative things can take the shine off it."
Villas-Boas said Lampard's performance was "fantastic" but added: "There are six players competing for those three positions [in midfield]. When we play with a number 10, it's even less. It's six players for two.
"Frank had a big, big day and it was important for him after the disappointment of coming out of the team against Napoli and Birmingham.
"He proved he can make the difference for the team. We always pick the team we think is best for the game and today he showed why he is one of the best.
"You [journalists] asked me directly at Napoli if Lamps was disappointed at missing the game and I assure you that he was, just like Raul [Meireles] was disappointed today - just like [Oriol Romeu] and [John] Obi Mikel."
