The Sun says Villas-Boas knows he can probably afford to leave Terry out against the Belgian minnows, who were buried 5-0 at the Bridge two weeks ago.
But he also knows that would raise more questions about the frame of mind of a player feeling the strain of a police and FA investigation after being accused of racially abusing QPR's Anton Ferdinand.
However, Villas-Boas insists the England captain has not been distracted by the allegations and continues to support his man.
Villas-Boas said: "We are always confident with any team we put out to win a game.
"Any 11 selected from 18 in the squad will be good. The Champions League is a different scenario to the Premiership and this is a good opportunity for us. We will put ourselves in a very good position to qualify if we win this."
