Ramos hit out at the tactics of coach Bernd Schuster and admitted he was "not enjoying playing" this term.
The defender told AS: "I'm very happy with the three years in Madrid and I think I've had a very high performance. People compare me with past performances and if I do not look the same, then people criticize.
"I mark myself between 6.5 and 7. And yes I think I can get to 9, as in other seasons.
"If I'm sincere, I do not now enjoy playing. Before I had the support of David Beckham and people who worked on the right and helped me a lot. Today, I am very very lonely on the flank and I'm being left on my own.
"Sergio is always the one who is wrong when goals go against us, even though I am left without cover. But I live with that and work to improve and solve this."
Despite his frustrations, Ramos says he is ready to sign his lifetime deal with Real. He added: "The club is talking with my brother. We were told it was going to be settled before Christmas.
"That gives me stability, tranquility and it would be a great recognition. People treat me with great affection."
