"The first thing is to give him some confidence; give him instructions of what he can do in a different way to improve him and the rest of the team a little bit physically," said Benitez.
Chelsea have managed just one clean sheet in their last 11 outings which came in Sunday's
0-0 draw with Manchester City
and Benitez believes that tightening up the defence will ease pressure on Torres having to score.
The former Liverpool manager also hinted he may change the shape of the side to help them improve defensively as Chelsea have used just 19 players in the Premier League - fewer than any other team.

"Chelsea were quite direct at times and some of the long balls up to him were not the best, and definitely not the sort he thrives on - those passes which let him pick up possession in the areas between the full-back and centre-back where he can be so effective."
