Martin O'Neill is unhappy about the relatively small number of tickets available to Ireland fans for the Euro 2016 last-16 match against France.
The Boys in Green face the hosts in Lyon tomorrow afternoon.
But the Irish supporters will occupy less than 10% of the seats in the Parc Olympique Lyonnais stadium.
"I think that the ticket allocation is something that I do have a gripe about," O'Neill commented.
"I think it's totally disproportionate for a stadium of this size and this brilliance for us or any team playing in the Round of 16 here to be allocated less than 5,000 tickets. I think it's pretty unfair really. I think it's totally disproportionate."
