Welcome to Eurosport-Yahoo!'s live minute-by-mnute coverage of the FA Cup fifth round replay between Arsenal and Leyton Orient at the Emirates Stadium!

Abou Diaby rolls his marker on the edge of the box and strikes... The shot is blocked en route to goal by Ben Chorley. Arsenal retain the ball but Orient play themselves out of defence well.

Early nervous moment for Manuel ALmunia as Kieron Gibbs underhits a pass back to the goalkeeper! The stand-in captain stays calm on the edge of his box and plays it back to the young England left-back.

Orient skipper Stephen Dawson gambols through and tries to prod the ball to Scott McGleish, but Ignaci Miquel helps tidy up.

Orient kick off and we're underway at the Emirates!

You'll be hard-pressed to find a better banner at the Emirates all season than the one which reads "Orient. Kids. Wife. In That Order"! The players are walking out on to the pitch now. We'll be underway shortly...

Mind you, not only are Orient undefeated in their last 13 games, but they are unbeaten in their last nine FA Cup matches away from home. Who knows what could happen tonight?

HEAD-TO-HEAD: These two sides have met 11 in all competitions. Arsenal have won seven, including four of their five previous FA Cup meetings. The draw at Brisbane Road was Orient's best result against the Gunners since beat them 1-0 1915!

This may be a dream for the Os, but Arsenal boss Arsene Wenger hopes his team can recover from their Carling Cup nightmare: "We have to live with the conclusions of people and keep our targets and goals. We are in a massive race in the championship, we have an opportunity to qualify in the FA Cup and we have won the first leg in the Champions League. We have much higher targets than the Carling Cup, even though we would have loved to have won it."

Orient chariman Barry Hearn is being typically bullish as he stands on the Emirates touchline admiring the stadium, but he is keeping his feet on the ground: "This is real David and Goliath stuff. We are realistic, but we are here. We have got absolutely no chance at all. but then, they said that at Brisbane Road too!" The sports impresario has already promised his players a trip to Las Vegas after they secured this replay which is set to net the club around £1m.

Tonight's referee is Lee Mason. The Bolton official is arguably the harshest disciplinarian in the Premier League, having dished out a whopping 73 bookings and three red cards in 16 Premier League matches so far this season.

Leyton Orient hero Jonathan Tehoue again only makes the bench. The French striker, who came on to grab a famous equaliser in the 1-1 draw at Brisbane Road last weekend, went home from training on Monday with a migraine, but has recovered. Captain Stephen Dawson was stretchered off 19 minutes into Saturday's 2-2 draw at Huddersfield with a knee injury, but he too has recovered and starts. Harry Kane is suspended after his weekend red card.

Arsenal hand a full debut to midfielder Conor Henderson tonight. The 19-year-old was on the bench for the 1-1 draw at Brisbane Road. Reserve team captain Ignasi Miquel retains his place from that match and partners Sebastien Squillaci at centre-back. Robin van Persie (knee), Cesc Fabregas (hamstring), Theo Walcott (ankle) Alex Song (knee) and Koscielny (hamstring) all miss out. Abou Diaby is back from suspension. Manuel Almunia replaces Szczesny and will captain the team tonight.

ARSENAL: Almunia; Eboue, Squillaci, Miquel, Gibbs; Diaby, Denilson, Rosicky, Henderson; Chamakh, Bendtner. Subs: Szczesny, Sagna, Nasri, Wilshere, Djourou, Clichy, Arshavin /// LEYTON ORIENT: Jones; Whing Chorley Forbes Daniels; Revell Dawson Crowe Carroll; Cox, McGleish. Subs: Omozusi, Chambers, Butcher, Spring, Tehoue, Cestor, M'poku.

The Gunner's hopes of an unprecedented quadruple were dashed at Wembley on Sunday when they lost 2-1 to Birmingham City in Sunday's Carling Cup final. Goalkeeper Wojciech Szczesny and defender Laurent Koscielny's combined calamity cost them the match in the 89th minute, and that pair are among several first-teamers who are rested against tonight's League One opponents.
