Everton head to Elland Road looking to progress to the next round of the Capital One Cup.
Here we preview the game by way of key numbers, statistics and historical facts.
2 Victories for Everton in the last 43 visits to Elland Road, since 1951. Good news is that David Moyes is unbeaten in both his trips to Yorkshire, with the Blues victorious 1-0 in November 2002, thanks to Wayne Rooney's goal, and a 1-1 draw during the following season. Our other win in that time was 2-0 in the FA Cup in January 1985.
4 Goals scored by Leeds in both our previous meetings in this competition. In January 1978 the Blues lost 4-1 at Elland Road in the quarter-final, after taking an early lead via Dave Thomas. In December 1991 Howard Wilkinson's men triumphed by the same score at Goodison in the fourth round.
5 Goals scored in our record away win in this competition, achieved on two occasions. In September 1967 Everton won 5-0 at Bristol City and 23 years later were victorious by the same score at Wrexham.
