The first leg ended 1-1, with the Blues getting a vital away goal in Spain, and go into Wednesday’s game with every chance of reaching their third Champions League final. Ramos is expected to return for the second-leg, and Tuchel has insisted he has a plan to deal with the Spaniard.
Tuchel told Chelsea's official website: "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."
Chelsea come into the game with multiple injury concerns. Antonio Rudiger sustained a facial injury in the first leg and Mateo Kovacic looks set to miss out on a reunion with his former club after suffering a setback in his recovery from a hamstring problem.
"For Toni, I think he will play with a mask. He trained on Saturday with a mask so it’s just about him getting used to it,” Tuchel added. "It will be a very tight race for Kovacic. He had a little setback and felt something in not the same area but the same muscle as before. It’s very likely that he will not make it unfortunately."
