Nuri Sahin struck a late winner as holders Liverpool beat West Brom in the third round of the Capital One Cup.
The Reds went behind early in the game 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 with winger Oussama Assaidi crossing for Sahin to tap in a winner.

The victory will provide Liverpool manager Brendan Rodgers, who will welcome former club Swansea to Anfield in the next round, with plenty of encouragement after he sent out a youthful side to begin the defence of the trophy they won last season.
And the introduction of Sinclair, who only celebrated his 16th birthday six days ago, after 82 minutes created a watershed moment in the Reds history as he replaced Jack Robinson as the club's youngest ever player.
Robinson, who made his debut for the Merseysiders at 16 years and 250 days, was part of Liverpool's starting line-up at The Hawthorns and epitomised the youthful look of the visitors' team.
Rodgers made 11 changes from Sunday's Premier League defeat by Manchester United, highlighting his main focus is Saturday's game against Norwich as his side chase a first top-flight win of the season.
The league campaign began badly for Rodgers when his side were beaten 3-0 by West Brom in August, as the Northern Irishman was handed a defeat in his first competitive game in charge of the Merseysiders.
