Nuri Sahin struck a late winner as holders Liverpool beat West Brom in the third round of the Capital One Cup.
The Reds quickly went behind when keeper Brad Jones dropped a free-kick and Gabriel Tamas drove in a shot.
Sahin levelled when his strike squirmed under keeper Ben Foster before striker Jerome Sinclair, 16, came on to become Liverpool's youngest ever player.
The visitors then produced a well-worked move and winger Oussama Assaidi crossed for Sahin to tap in a winner.
