RED STAR BELGRADE fans "displayed a Russian flag" at Ibrox last night, according to a report. 

The 900-strong travelling support from Serbia were housed in the away corner of the stadium. 

Despite being in full voice for the entire game, they were left bitterly disappointed as Rangers ran out 3-0 winners in the first leg of the last-16 Europa League tie. 

Goals from James Tavernier, Alfredo Morelos and Leon Balogun were enough to secure the vital advantage for Giovanni van Bronckhorst's men going into the second leg in Belgrade next Thursday. 

The Serbs could count themselves a bit unlucky though, as they saw three goals chopped off for offside calls made by VAR.

And the night seemingly didn't improve for Red Star at full-time. 

The Scottish Sun say that images have shown the players clashing with stewards at the end of the game. 

The report states that they were prevented from going to embrace their supporters in the aftermath of the match.

The Red Star fans are renowned throughout the world as being one of the most hardcore supports in football.

And the report also states that with Serbia's connection to Russia, a Russian flag was apparently displayed in the away end at Ibrox on Thursday night.

The Serbian champions display Russian oil giants Gazprom on their shirts, having refused to remove the branding as other clubs have done in the wake of the country's invasion of Ukraine.
