Red Star Belgrade have taken to social media to ramp up their Europa League league rivalry with Rangers.
The Serbian giants visit Scotland next month before hosting Gio van Bronckhorst 's side in the return leg at the Marakana.
The Ibrox side sealed the the shock of the round to send favourites Borussia Dortmund out of the Europa League with a 6-4 aggregate win.
That will have got some Rangers fans dreaming of a run in the competition - and some overzealous supporters have been telling Red Star exactly what they think of them.
One punter messaged the FK Crvena zvezda English account branding the former European Cup winners a "small club".
The Serbian champions didn't take the DM lying down and posted a tongue-in-cheek response to the comment.
The Red Star post read: "A bloke called Ross slid into our DMs with this message.
"We have been deeply affected by the news about us being a small club. We'll be taking a break from Twitter until further notice. Thank you."
The first leg of the last 16 Europa League clash between the sides will take place on March 10.
