Tottenham earned progress to the UEFA Cup knockout phase after last night's 1-1 draw at Anderlecht.
Spurs will be mentioned among the favourites for the tournament but Ramos said: "We're far from achieving this. We have to wait for the draw, we have to get better because we look a bit vulnerable."
Assistant boss Gus Poyet said there was calmness in the dressing room after the incidents that soured qualification.
"I think it's not good for Anderlecht," he said.
"It's nothing to do with Anderlecht, there are always a few people.
"The lads were calm but they know how dangerous the situation could be."
