The French club says they expect exemplary behaviour from their fans
Olympique Lyon, Barca's Champions League rivals, have confirmed they expect 5,000 fans to travel to Catalonia for the match on Wednesday.
"All the tickets given to Lyon have been sold, the fans have mobilised, individually or in groups, to travel to Barcelona and 15 coaches are heading to Camp Nou," said Lyon on their website.
The club have also decreed that French fans must collect the tickets from the Barcelona Centre hotel on Balmes.
"The club thanks its fans for their huge and unconditional support, and counts on exemplary behaviour to elevate the values and sporting colours of Olympique Lyonnais," Lyon added.
