Ahead of this evening's Emirates FA Cup fourth-round clash with West Ham United at Anfield, here are 14 key facts you should know about the game from club statistician Ged Rea…

The Reds are seven times winners of this competition, last lifting the trophy in 2006 after beating today's opponents on penalties in Cardiff. It was Liverpool's 13th of 14 final appearances and the Hammers' fifth.

The last Liverpool hat-trick in the FA Cup was scored by former Hammers midfielder Yossi Benayoun against non-league Havant & Waterlooville in the fourth round in 2008.

The Reds used 18 players in the two games with Exeter in round three.

Since winning the FA Cup in 1992, Liverpool have suffered nine FA Cup defeats at home.

10 days ago in the third-round replay with Exeter, Sheyi Ojo netted to become the youngest player ever to score for the Reds in the FA Cup. He was 18 years and 215 days when bagging the second in the 3-0 win.

Three of Liverpool's last five home games have been settled by a single goal. They have beaten Leicester 1-0 and lost by the same score to Manchester United and Stoke. Those two defeats have come in the last three games at Anfield.

Liverpool have won two of the last six fixtures on home soil.

This season, West Ham recorded their first league double over the Reds since 1963-64 and only their third in total.

The Hammers could make history in this tie by beating Liverpool three times in one season for the first time ever.

Slaven Bilic has won his last three games as a manager against Liverpool losing only once, at Anfield to a late penalty last season while in charge of Besiktas.

West Ham have won the trophy three times - in 1964, 1975 and 1980. In 1923 and 2006 they were beaten finalists.

Away from home in the FA Cup, the Hammers have won two of their last 10 games on the road, losing seven.

In their last seven FA Cup ties with fellow Premier League teams West Ham have won just once - they beat Everton on penalties in round three last season.

Away from home this season, the Hammers have won one of their last seven in all competitions - a 3-1 victory at Bournemouth earlier this month.
