Orient Hold The Gunners

In Saturday's early kick-off, holders Chelsea were knocked out of the competition after losing their fourth-round replay against Everton on penalties.

After a goalless 90 minutes at Stamford Bridge, Frank Lampard gave the holders the lead in the first-half of extra-time before Leighton Baines curled home a superb 25-yard free-kick in the last minute to take the match to a shootout.

Baines then saw his spot-kick - Everton's first - saved by Petr Cech, but Nicolas Anelka's effort was superbly saved by Tim Howard before Ashley Cole fired Chelsea's fifth penalty over the bar to allow Phil Neville to seal a 4-3 shootout win.

Everton will now face Reading at Goodison Park in their fifth-round match on Tuesday 1st March.

In Saturday's fifth round matches, Birmingham City and Stoke City successfully navigated their way past lower league opposition, with each team enjoying a 3-0 win.

Birmingham cruised into the quarter-finals of the FA Cup for the second successive season after their win over Sheffield Wednesday  - but Alexander Hleb could be facing Wembley heartbreak.

Hleb set up the first two goals for Jean Beausejour and Obafemi Martins but was then stretchered off and looks doubtful for next weekend's Carling Cup final with his former club Arsenal.

Full-back David Murphy scored the third goal early in the second period and Birmingham were comfortable winners despite making eight changes.

Meanwhile, Stoke sealed their place in the sixth round with a comfortable victory over Brighton and Hove Albion at the Britannia Stadium.

The visitors were undone by three first-half headers, with John Carew netting after 14 minutes and his strike partner Jon Walters making it 2-0 eight minutes later.

Walters then set up Potters captain Ryan Shawcross just before the interval, and although Brighton improved in the second period, they were unable to reduce the deficit.

Finally, Richard Brodie hit the bar in stoppage time as non-league Crawley Town narrowly failed to take Manchester United to an FA Cup replay.

Wes Brown's first-half header proved enough for United, who struggled to cope with Crawley's tenacity.

On Sunday, two headers either side of half-time from Manchester City midfielder Patrick Vieira and late efforts from Carlos Tevez, Edin Dzeko and Micah Richards disposed of Notts County in their FA Cup fourth-round replay at Eastlands.

Vieira, a four-time FA Cup winner with Arsenal, struck in the 37th and 58th minutes before substitute Tevez, Dzeko and Richards finished things off in the final six minutes.

County had dominated early on, hitting a post through Karl Howley, but the Premier League side upped their game to run out comfortable winners.

Ivan Klasnic's second FA Cup goal in four days secured Bolton Wanderers a 1-0 victory over Fulham and a quarter final trip to Birmingham City.

The Croatian striker scored the winner in Wednesday's fourth-round replay against Wigan Athletic and he was on hand again here to volley home from 12 yards.

Fulham welcomed Bobby Zamora back into action after five months out with a broken leg but they could not find a breakthrough in a fractious encounter at Craven Cottage.

Leyton Orient handed Arsenal a reality check as the League One side battled to a famous 1-1 draw in their FA Cup fifth-round tie at Brisbane Road.

The Gunners made 10 changes from the side which had beaten Barcelona in midweek, but lacked a cutting edge in attack before they eventually made the breakthrough when Tomas Rosicky headed in on 53 minutes.

However, Orient produced a late rally and earned themselves a replay when substitute Jonathan Tehoue drilled home with a minute left to keep alive the dream of a quarter-final at Manchester United.
