Kalou had no doubt Torres would prove a success at Chelsea.
He said after victory at Benfica: "That's the second goal that he gave me.
"Against Leicester also, he gave me an assist, so there is a good understanding between us.
"I'm glad he's playing, he's enjoying.
"For me, he's still the striker he used to be and he just has to keep doing the hard work and the best is to come."
