The money from an FA Cup run might not make too much difference to teams like Arsenal, Chelsea or Manchester City, but a good cup run can secure a non-league team's future for years to come.

Winners at this stage receive £12,500, but just what is the maths behind a jackpot FA Cup run?

Brentwood. A town in Essex that has become famous, or maybe infamous, for being the setting of the fake-tan loving, nightclub going, emotional relationship-falling-apart 'stars' of reality television programme The Only Way Is Essex.

But today the town's footballers could become stars (sort of) as they aim to reach the first round proper for the first time.

Managed by former Wimbledon and Bolton striker Dean Holdsworth, Isthmian League Brentwood travel to face Didcot Town, who are one level below them in the non-league football pyramid and are the second-lowest ranked side left in the competition.

Forest Green are back in front at Margate with a diving header from Curtis Guthrie. Margate were level for three minutes.

This could be a very lively bus later. Maybe.

GOALLLLLLLLLLLL

The home fans are delighted as the away team's defence is carved open and a lofted finish from Luke Moore from the edge of the area brings Margate level. Twenty minutes left.

Remember, Margate are a division below the National League leaders.

BBC Radio 1 Xtra DJ Nick Bright is having a relaxing time at Altrincham so far if this picture is anything to go by.

Nick will be speaking to the key people and a number of fans during Altrincham's match against Chester. Remember, some of that footage will be shown on Final Score from 16:00 BST on BBC One this afternoon.

Tranmere Rovers have reached the FA Cup quarter-finals three times since 2000, but recent seasons have been pretty miserable. Today they have to play their first match in an FA Cup qualifying round since 1924.

But are they moping about feeling sorry for themselves? No way? It sounds like Prenton Park is going to be a very fun place to be today as they welcome fellow National League side Lincoln City.

Alan Devonshire is certainly someone who knows about the romance of the FA Cup.

He played in West Ham United's 1-0 win over Arsenal at Wembley in the 1980 FA Cup final.

But it is York Road for him today, as he is the manager of Maidenhead United, who face Woking.

The BBC WM van looks a bit close to the pitch for my liking. They will be hoping no wayward free-kicks wipe out the satellite dish.

It remains one of the biggest shocks in FA Cup history.

Non-league Sutton United knocked out top-flight side Coventry City 2-1 in the third round of the 1989 competition as 8,000 people squeezed into Sutton's Borough Sports Ground home.

Sutton are on the road today though. And again it will be a shock if they win, albeit not as big as 26 years ago, when they face Aldershot.

This was the scene at Boreham Wood yesterday evening as they prepare for the visit of Essex side AFC Hornchurch.

There are three divisions between the sides, but Boreham Wood are struggling in the National League, while Hornchurch are third in Division One North of the Isthmian League. Will this be the setting for a cup shock? Stay with us and we will find out.

We are back under way at Margate for the second half. The Kent side trail 1-0 to Forest Green Rovers courtesy of Keanu Marsh-Brown's goal at the end of the first half.

It was nearly the FA Cup shock to beat all FA Cup shocks. Mighty Liverpool fell behind at home to Blue Square South Havant and Waterlooville, not once, but twice, at Anfield during their fourth-round tie in 2008.

Havant led until the 44th minute, before losing 5-2.

The Hawks are hoping for another magic moment today when they face a Cheltenham side second in the National League.

I have to admit this Mr Pooch, I'm a little bit scared.

Some good work to highlight from the media team at Chippenham Town. They have produced a BBC-style montage with a dramatic musical soundtrack showing some of the club's best goals and celebrations.

The Southern League side say they are ready. They will need to be against a Maidstone side a division above them.

The montage is well worth a watch., external

Think Arsene Wenger has been in the manager's job at Arsenal for a long time?

Well, he's got nothing on Wealdstone's Gordon Bartlett, who has been in charge of the National League South club since June 1995, one year and two months before Wenger took over at the Gunners.

Bartlett is aiming to reach the first round proper for only the second time at Wealdstone as they entertain Bognor Regis Town. Will the Stones be rolling into the next round?

We are filming the action from Altrincham, including behind-the-scenes footage ranging from the dressing room to the stands.

Some of the footage will be broadcast later on today on Final Score, which is on BBC One from 16:00 BST.

Football fans can be a cruel bunch. So you have to have some sympathy for Alex Ferguson. Not that one. The Chippenham Town midfielder of course.

"Whenever my name is read out over the speakers before a game I think 'here we go' because it always provokes a reaction from opposition fans.

"Sometimes it's good but there's always a few jeers too."

Read more on the other Alex Ferguson here.

We have our first goal of the day. And it is a goal for National League leaders Forest Green Rovers, with the goal coming from Keanu Marsh-Brown.

It is not the biggest dressing room ever, but this could be the scene later for some incredible celebrations if Sporting Khalsa move into the first round proper.
