SPARTA PRAGUE supporters have been urged to 'think carefully' when deciding whether or not to travel to Glasgow for their Europa League clash with Rangers on 25 November.

The two sides met in a Group A encounter last week but the match was marred after Glen Kamara - the Finnish midfielder who was racially abused by Slavia Prague's Ondrej Kudela in the same competition earlier this year - was subjected to boos from the home crowd.

The game was supposed to be played behind closed doors after Slavia were charged by UEFA for a racist incident in a previous European fixture, although the Czechs were given special dispensation from the continent's governing body to allow 10,000 schoolchildren to attend the match.

The coverage of the abuse Kamara received in Prague by the Scottish media provoked a furious reaction in the Czech Republic, with Sparta issuing a statement where the club demanded "stop abusing our children".

The two incidents involving Kamara have increased tension between Scottish football and the Czechs, prompting minister of the interior Jan Hamacek to urge fans to carefully consider making the trip to Ibrox.

"We have taken steps that should lead to an increase in the security of Czech citizens in Scotland," Hamacek told Czech news outlet iSport.

"I expect Sparta Prague fans to want to support the team. I would like to encourage them to consider their visit to Scotland and think carefully due to the aggravated situation after the first game between both teams.

"In a letter, I also addressed the Scottish Home Secretary and asked him to pay attention to the security of Czech citizens in Scotland.

"They can be fans, tourists, but also people on business trips."
