Liverpool boss Jurgen Klopp has questioned why almost half the tickets for the Champions League final against Real Madrid are not allocated to the clubs.
Klopp's side face the Spanish giants on 28 May and have 19,618 tickets to sell.
That is 26.1% of the 75,000 capacity on the night at Paris' Stade de France.
Klopp said: "Is it right that we only get 20,000, they get 20,000 and there's 75,000 in? That makes 35,000 left over. Where are these tickets?"
Uefa sell 12,000 tickets to fans worldwide but the window for these sales closed on 28 April, days before Liverpool and Real Madrid fans knew their team was in the final.
The remaining 23,000 tickets will be distributed to national associations, commercial partners, broadcasters, and Uefa's official hospitality programme.
Hospitality tickets have now sold out but were still available on Thursday, ranging in price on Uefa's website from 4,900 euros (£4,178) to 8,900 euros (£7,590).
