The two teams meet in the competition's quarterfinals.
Ramos said: "Galatasaray are a pretty strong team and their new signings make them a force to be reckoned with; we have to give them a lot of respect.
"We will try to keep a clean sheet at home and score away goals because things will be difficult on their turf. I have an itch I want to scratch and that is to be able to touch and raise the Champions League trophy. It is one of my greatest dreams that I can have at this stage of my career."
