Videos on social media showed supporters clashing on a side street with tables, chairs and bottles being thrown before riot police arrived on the scene.
Seven Serbia fans were also arrested after violent clashes.
Mr Thomas, from Little Lever, told the court he was handed papers informing him the police were applying for a banning order when his passport was taken at the airport.
District Judge Joanne Hirst asked the defendant: “Do you oppose this application?”
Mr Thomas replied: “Well, I have not seen what they said I have done.”
The judge said police had applied to impose the ‘Football Banning Order’ (FBO) as “it is said they can provide evidence you caused or contributed to disorder in the UK or elsewhere”.
She added: “Obviously, you need to know exactly what you are being accused of.
“I understand there’s some CCTV, some statements, will be sent to you.
“Football Banning Orders are quite draconian. It would be a minimum of three years and stop you going to a football match for three years.
“It will be so that further violence will not be caused.”
