Torres scored his first competitive goal since April to beat West Brom and Lucas hopes it will be the first of many this season.
"That's what we expect from Fernando," said the Brazilian midfielder.
"When Fernando strikes a ball at goal always it is difficult for any goalkeeper. He showed again he is a top class striker and we hope he can now get many goals for us between now and the end of the season.
"He has showed a lot of quality since he came to Liverpool. He is also a really nice man and a really good professional and we are happy to have him in our team."
