Mischievous fans of rival teams have flocked to Liverpool's official online store to buy the club out of beach balls.
The Reds lost 1-0 to Sunderland on Saturday courtesy of a Darren Bent strike that deflected in off a large red ball that had been thrown into the penalty box by a Liverpool supporter.
Opposition fans revelling in Rafa Benitez's side's misery have bought all remaining 'beach sets' from the online shop, which consist of a towel, a bag and the now-infamous beach ball.
The sets had been reduced from £20 to £10 and have now sold out. They will be a must-have item for travelling supporters visiting Anfield in coming weeks.
Several web users have also left spoof reviews on the site.
'Natalie from Manchester' wrote: "I bought this set, but seem to have lost the ball in Sunderland. Is it possible to order a replacement?" while 'G from Johnon' commented: "This is one of the most flexible products I have ever purchased. Great for not only the beach, but can also play up front."
Liverpool fans are unlikely to see the funny side; the defeat was their fourth of the season, and leaves them seven points off the top of the Premier League.
