Oscar is expected to play as a second striker behind the Spaniard against Tottenham tonight.
"On Tuesday we were working with Torres and with Oscar and we are trying to find this understanding," Benitez said. "But it will take some time. We were also working on some little movements for David Luiz, for Ashley Cole, for Eden Hazard and others - we are trying to improve each player a little bit but then we have to put them together.
"We can talk about the striker but we have to create more chances. If we create more chances and afterwards he is not scoring, I will analyse why. Then we will continue."
