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