Ramsey left Villa for Newcastle on the weekend.
Senior defender Tyrone Mings took to social media to urge fans not to react negatively towards his former teammate.
He posted: "Don't wanna hear any bad words or anything negative on his name.
"You don't know the half (of it)."
Meanwhile, Villa captain John McGinn also wrote on social media: "Always humble, respectful and willing to learn.
"It’s been a privilege to share the dressing room with you and enjoy some special moments together on the pitch.
"A sad day losing a top player and person and one of our own but it seems to be the way football is set up these days."
