Millwall have got their tails up and Brighton's lone striker is stood on the half way line. It's been a really good start by the hosts.

Millwall are playing nice football. Jed Wallace flicks one around the corner with a backheel to create another good position in a wide area.

It's just that final ball which is letting them down.

Brighton need to settle things down now, get the ball down, show their Premier League quality to their advantage. They need to quieten things down in the stadium.

Dale Stephens has just had a shot from at least 40 yards for Brighton.

Ambitious.

It was comfortably blocked before it got to the penalty box.

Brighton win a free-kick but the delivery from the left is really poor. The cross is easily cut out.

Shane Ferguson then sets off on a direct run down the left and is brought down. The Millwall fans near the touchline leap out of their seats and call for a yellow card.

It's just a free-kick and it comes to nothing.

You can see Millwall's game plan. They are making Brighton's defenders turn by putting pressure on them in areas they do not want to be in.

There are smiles on the faces of the Millwall players. They're loving this. Lee Gregory has a pop from the edge of the box. The ball cannons off a yellow Brighton shirt but inexplicably a goal kick is given.

Chris Hughton will be worried by this start, Millwall are looking like the side playing with a Premier League team's confidence.

Millwall are right on this early. It's an exceptional start. Brighton have not been allowed to settle. Mahlon Romeo gets in down the right side of the box but his cross is cut out.

It's a hostile atmosphere and the crowd are up for it. It was a good start by Millwall who were on the front foot there, playing in the Brighton box.

Millwall's start only sees the noise levels increase further. The home side are on the front foot right away. Centre forward and top scorer Lee Gregory gets up well to challenge Brighton's centre-backs. Strong start.

Brighton's recent win will have made them feel a bit more comfortable, and helped Chris Hughton pick a stronger side today.

Away we go.

Wembley awaits.

Millwall manager Neil Harris told BBC Radio 5 Live: "Everyone is going to come here and enjoy the occasion today. This is a welcome relief for us as a Championship club and we'll give a good account of ourselves today.

"We are playing against a good Brighton side that have performed really well in the Premier League. Our fans will get behind our players and we have to make it as difficult for Brighton, but we have good pedigree here having beaten some big teams."

And now the players emerge into the Lion's Den.

The home fans are all chanting in unison. There are cries of "Aaaaaalbionnn" from the away end.

This should be good.

The players are side-by-side in Millwall's dark, cramped tunnel. The Brighton players look relaxed.

Ex-Brighton striker on BBC Sussex

Brighton have been drawn against the lowest ranked team, we needed to play a strong side, and we have. Turn up, and Brighton could win this easily. Don’t turn up, and we could be in trouble, especially with their home crowd.
