Manchester United is the only licensed agent to sell tickets in the away end of a ground in the FA Cup or Premier League involving United.
Yet Champions Travelclaims to be able to sell them – at £145.81.
The firm does not allow customers to buy tickets individually – you must instead buy ticket and hotel packages.
You can either stay in the three-star Days Inn or the four-star Novotel in Liverpool city centre.
If you were to book using booking.com, a single room with breakfast in the Days Inn on a typical Saturday night costs £99.
A single room with breakfast in the Novotel on a typical Saturday night costs £115.
The match ticket face value is £38.
So that should mean a ticket and a night at the Days Inn costing £137 and a ticket a night at the Novotel costing £153.
But Champions Travel is charging £244.31 for the Days Inn package – a mark up of £107.31.
The firm is charging £260.81 for the Novotel package – a mark up of £107.81.
That in effect means fans are being asked to pay up to £145.81 for a ticket.
UPDATE: Since Reds Away contacted the FA (who have revealed it is not a licensed ticket agent) Champions Travel has removed its away-end tickets for sale from its website.
However, there is always the possibility such firms may deal over the phone or via email, though there is absolutely no suggestion that Champions Travel has done so.
