A Shaun Maloney penalty has given Wigan Athletic an unlikely 1-0 lead over Liverpool at the interval.
It was Liverpool who started the match the better and Stewart Downing might have opened the scoring after just six minutes, but his strike was smartly blocked by James McArthur.
Wigan remained a threat, however, and Victor Moses might have scored after ten minutes, but Martin Skrtel was on hand to make the block.
Wigan were awarded a penalty after 30 minutes when Skrtel felled Moses in the box, and Maloney stepped up to send the away side into the lead.
Liverpool continued to push for the equaliser in the latter stages of the half, with the Anfield crowd beginning to air their frustrations.
