Lyon go to Turin for the second-leg of this Champions League round 16 tie defending a 1-0 lead from last night.
But Ramsey says: "We knew it would be a difficult game.
"They have excellent players and have exploited their qualities. We tried to break down their wall, but we didn't succeed. We are in the tie, there is still a long way to go.
"We believe in the comeback, with the help of our fans we can go through."
