Red Star warned of Rangers 'thunder' as Celtic insider highlights two key danger men

Celtic coach Miodrag Krivokapic has told Red Star they face a thunderous welcome at Ibrox after drawing Rangers in the Europa League.

The Serbian giants visit Scotland next month before hosting Gio van Bronckhorst 's side in the return leg at the Marakana.

Red Star's home ground is famous throughout the world for its intimidating atmosphere but Krivokapic, who is involved in youth development for Celtic, expects fireworks in both matches.

"Ibrox thundered in all 90 minutes of the second leg with Borussia, 50,000 supporters in the stands.

"The picture will, of course, be repeated for the visit of the Red Star.

"We also know what kind of spectacle, what kind of fan party, the Serbian fans know how to put on in their own back yard..."

And Krivokapic told his compatriots that they'll have a real battle on their hands, as he highlighted Ryan Kent and Alfredo Morelos as two to watch.

He explained: "They're a good team. Defense, midfield, attack, everything in place.

"What other testimony do you need than the Borussia Dortmund result?

"In the foreground is the Colombian international Alfredo Morelos, who had problems with discipline during Steven Gerrard's tenure, but is now playing his best football since he came to Glasgow.

"Physically strong, at first glance he seems heavy, but he's not. He is also fast, he has a great eye goal, he loves a battle, and is decent in the air too.

"I would also like to mention the young, talented Ryan Kent, dangerous on the wing.

"The guy is like lightning, explosive, full of energy, and also makes good decisions.

"Then there's James Tavernier, right back,
