Kalou goal keeps Chelsea in hunt

 In another of the weekend's five all-Premier League ties Aston Villa beat Blackburn Rovers 3-1 in a repeat result of their third-round meeting a year ago. All their goals came in the first half from Ciaran Clark, Robert Pires, who won the Cup three times with Arsenal, and Nathan Delfouneso.

Leyton Orient, struggling at the wrong end of League One (third division), pulled off a second successive upset win when, having knocked out Norwich City away from home in the last round, they won 2-1 at Championship (second division) promotion-chasers Swansea.

Manchester United, 11-times winners, visit League One Southampton later on Saturday in a repeat of the 1976 final when then-second division Southampton claimed a shock 1-0 win.
Chelsea, bidding to be the first team to win the FA Cup in three successive seasons since Blackburn Rovers managed it in 1884-86, lacked urgency and looked more like the team who struggled so badly in December than the one who had had won their last two league games.

Everton, who have won one and drawn four of the teams’ last five Premier League meetings but did lose to the Londoners in the 2009 final, took control and Petr Cech did well to keep out a header from the dangerous Marouane Fellaini.

Everton broke through after 62 minutes when Saha met a Leighton Baines corner to power a header past Cech.

With youngster Jack Rodwell outclassing Michael Essien in midfield Everton remained on top and Seamus Coleman was twice denied by Cech and then a John Terry block.
