That's three excellent crosses already from Portsmouth winger Ricky Holmes. Again the vast blonde mop of defender Jack Whatmough is up there attacking the ball, but this time he can't connect. All Pompey so far.

Portsmouth go close again! What a start, frantic defending from the Shots as Ricky Holmes can't force the ball in at the far post. The League Two side hitting top gear.

Pompey boss Andy Awford said that he wanted this tie put to bed as soon as possible and they almost score in the first minute. Ricky Holmes' free-kick is deep, Jack Whatmough wins the header and it's cleared off the line!

Pompey get this show on the road. False start! Referee Stuart Attwell blows up and they have to retake it. Hopefully not an omen...

A banner reading 'Against modern football' is hoisted high in the stands behind the goal. Old-fashioned rough-and-tumble stuff will do us tonight. A chilly, visible-breath sort of night in Hampshire.

Almost game time at the Rec. A reminder that the winner tonight faces Rochdale in Round Two. We could have extra-time and penalties this evening, though I have to say that I'm all for Andy Awford's plans to put this tie to bed one way or the other inside the 90 minutes.

May the best team win...

Danny from Epsom: Come on you Shots! Time to give this 'Portsmouth' team a footballing masterclass and set up mighty tie with Rochdale!

Chris from Esher: Aldershot can win this, we've got to the 4th round in 2012 I'm sure we can get there in 2014! COME ON YOU SHOTS!

Don't forget you can watch every goal - in every round - of this season's FA Cup on the BBC Sport website and app.

Portsmouth manager Andy Awford: "I was the youngest player to play in the FA Cup a long time ago! This is a magical competition. We've been fortunate to win it and get to finals in recent years but we are where we are now.

"We are a League Two club. The mission is to get into the hat, nobody wants penalties, we want to win this tie and put it to bed in 90 minutes."

Around 40 miles and one division separate the two clubs in action this evening - can the Shots cause an upset?

Manager Andy Scott thinks so He says: "It's been a difficult two years but it's nice to have the cameras here this evening.

"We played really well in the first game and went ahead - we just couldn't hold on. Confidence is high and we will give them a good game."

As an added bonus this evening, you will be able to see the goals from this game within minutes of the ball hitting the net.

Keep your eyes peeled on the 'highlights' tab for videos of the latest action.

Aldershot Town manager Andy Scott told BBC Surrey:

"We are going to have a near sell-out, which is a fantastic effort from everybody really and shows what the feeling is around the place.

"You want to be involved in the big games with the big atmospheres. This is a reward for saving the club and goes to prove there is life in us yet.

"We want to put on a good show and show how good we are as a group.

"Although it can't exactly be classed as a Cup run yet, the finances have massively boosted us and it has given the players confidence."

Dave from Aldershot: Come on you Shots! Fancy Aldershot to sneak a cheeky win here, I've never even heard of Portsmouth.

The big game at the Rec may be the only FA Cup action this evening, but there were plenty of replays last night.

Non-league Southport reached round two for the first time since 2002 by upsetting League Two Dagenham & Redbridge, while fellow Conference side Telford beat Basingstoke to progress.

Conference South side Concord Rangers also drew 1-1 at League Two Mansfield - 44 places above them in the football pyramid - to force a replay.

From Cup winners courting Peter Crouch and Jermain Defoe to roughing it out with the non-league lads in six short years. Portsmouth's slump is enough to test the patience and sanity of even the most committed fan.

But what are sport's biggest falls from grace? Who had it all, the world at their feet, only to spectacularly bin it? Sometimes through no fault of their own.

Suggestions please. Two starter points for identifying this gentleman in the magnificent shirt...

As if Portsmouth's slide down the rungs of the footballing ladder wasn't painful enough, they may not even be favourites tonight.

Marooned in 13th place in League Two, they face a team exactly one division below them but in good form. Andy Scott's Shots have lost one of their last seven games in all competitions, including the 2-2 draw in the first meeting at Fratton Park.

The Shots will fancy another home win tonight.

Three changes for Aldershot from the team which beat Nuneaton. Mark Molesley, Jaydon Gibbs and Jordan Roberts return to the starting XI.

Aldershot: Smith, Gibbs, Oastler, Barker, Wilson, Molesley, Oyeleke, Forbes, Roberts, Holman, Williams
