Paris Saint-Germain have been called before UEFA's disciplinary commission following allegations of discimination by supporters during the first leg of their Champions League quarter-final tie with Chelsea held in Paris.

Five Chelsea fans with disabilities allege that they were subjected to abuse throughout the match. The allegations are understood to include claims that PSG fans threw a bottle and spat at their disabled visitors.

If found guilty PSG could be subject to a fine or partial stadium closure during European matches. A UEFA statement yesterday read: "Disciplinary proceedings have been opened against PSG for alleged offences concerning 'racism, other discriminatory conduct and propaganda' at their UEFA Champions League quarter-final played against Chelsea in Paris.

"The UEFA control and disciplinary body will decide on the matter on 17 July 2014."
