Linked with moves away have been forwards Nicolas Anelka, Salomon Kalou and Malouda, the latter of whom came off the bench to score the winner against West Brom on Saturday having lost his place in the side.
Malouda played down the implications of being left out and of Kalou being withdrawn for him after just 35 minutes against West Bromwich Albion.
He told his club's official website, chelseafc.com: "It has always been clear before this game that there is a lot of competition in the squad. Everyone is under pressure.
"It is nothing new and I think it will be like this throughout the season.
"He [Villas-Boas] asked a couple of simple questions at half-time. 'Do you think that is how we want to play and is that what we want to demonstrate to the other teams who want to win the title? Are we ready to change things?'
"It was a simple but very efficient message. We had to take more risks and play with more character."
