City fought back from a goal down to win the first-leg of their Champions League round 16 tie 2-1 in Madrid.
There's been complaints from the hosts that Gabriel pushed Ramos before scoring City's equaliser.
But Gabriel said at the final whistle: "This is a contact sport, I didn't push, I barely supported myself with my hands - just as it looks.
"I placed my hands (on Ramos' back) that's all.
"Ramos was not fouled."
