"In the last three games he was really good, he is improving his mentality, work-rate and movement and he is now showing his ability but I think he can do it better," said Benítez.
Premier League: club-by-club 2008/09Liverpools Fernando Torres denies any chance of a move to Manchester United "The main thing is the mentality of the player. He is keen to learn and he will improve but how much depends on him."
Benítez said he was always confident the 25-year-old would become one of the world's greatest strikers after bringing him to Anfield from Atletico Madrid in the summer of 2007.
"If you think about the money we were spending on players we then decided to spend £20 million on Torres that was a massive figure for us," admitted the Spaniard.
"We decided to bring him here because of his quality but also his potential and the future he had.
"We had a lot of confidence he would get better and we are pleased now but he can improve."
Liverpool are the Premier League's leading scorers this season, and Benítez is suitably impressed by his side's attacking prowess.
"The team was playing with confidence, creating a lot of chances and at the end of the game we could change players and think about the next game.
"Six goals is fantastic but it could have been even better because we had more chances at the end.
"The positive thing was the mentality of the team going forward, trying to win the game and still trying to score more goals."
