UEFA has hit Scottish champions Rangers with a second charge of “discriminatory behaviour” over their fans’ sectarian chants during Europa League matches.

UEFA said yesterday it is investigating incidents during the second leg of the last-16 series against PSV Eindhoven on 17 March in Glasgow.

Last week, Rangers revealed they had been charged by UEFA following the first leg in the Netherlands on 10 March.

Rangers chief executive Martin Bain said he was “absolutely astounded” by the second case.

“We are still in the process of preparing our submission on the away game and to be confronted with this now seems chaotic to say the least,” Bain said in a statement on the club’s website.

Rangers, who ahve previously been fined by UEFA over religious chants, said they face a punishment of playing two European matches in an empty stadium next season. The club would lose millions of pounds in revenue if its 50,000-capacity Ibrox home was closed.

UEFA’s disciplinary panel will hear both cases on 28 April.
