"Despite a poor start to the season, what followed was a more united group - more eager, more enthusiastic, more ambitious to keep improving, doing things right," Ramos told UEFA.com.
"But we can't set off the fireworks just yet because we haven't achieved anything. So we are putting in the same amount of work and concentration.
"We want to finish the season by experiencing victories and above all by winning trophies."
The second leg of the tie will be played in Istanbul on Tuesday.
