However, the Spaniard, who is believed to have instigated the meeting, has insisted that the team are "fully behind" boss Carlo Ancelotti.
"The purpose of the meeting is not important. It is the effectiveness that it is likely to have. As Cristiano [Ronaldo] said a few days ago, we are fully behind the coach and we are all responsible. We have to be together and draw positive conclusions," Ramos told reporters at a press conference.
"The fans' criticism of the team is normal. We know how demanding our fans have been over the years, but we understand. The fans are used to seeing their team play well. They rely on the team and know that we can give more. We must return their ambition.
"Nobody doubts that Madrid will be up there challenging for the trophies at the end of the season because we have a great team. We aspire to win all three titles. It is too early in the season, whilst the season is also very long."
