Chelsea boss Thomas Tuchel admits he could go with a false 9 for their Champions League clash with Real Madrid this week.
Chelsea will host Real Madrid in the second-leg with the aggregate score locked at 1-1.
Tuchel said, "If we play with no striker at all and Ramos has nothing to fight then that can also be a solution.
"I have not made my mind up yet.
"It's another challenge because he is the leader of their group and he is the guy to give a lot of solutions to any questions that we will hopefully ask them.
"We will wait and see who is in good shape and good form, what shape we play and where we try to hurt them. I'm not too sure if they will play again with five or go back to four [in defence] so there are many questions but we don't need the answers now. It's enough if we have them on Wednesday."
