Thierry Small bursts down the right for Charlton and Luke Leahy wins the tackle but then loses control of the ball to concede a throw-in.

It's a long one into the box and Wycombe hack it away.

Charton have got a foothold now after a wobbly start.

I could be getting carried away by the atmosphere but even with 12 minutes gone this feels like a better game than Sunday's first leg.

Those who sat through that will know what I mean...

Charlton earn their first corner which, like Wycombe earlier, they take short and which, like Wycombe, comes to nothing.

Just sling it in lads!

Charlton won both the games between these two in the regular season and it was a 2-1 victory in South London on 29 December.

Anything like that and they'll be delighted tonight.

Skipper Greg Docherty has their first shot but it's a weak one easily gathered by Franco Ravizzoli.

What a brilliant start from Wycombe, it has hardly been out the Charlton half.

An early goal here would really silence the crowd.

Wycombe boss Mike Dodds was keen to stress they need to handle the atmosphere tonight and they've certainly made a decent start.

Charlton haven't been in their opponent's half yet.

The West Stand that curves around to meet the North Stand everyone in the bottom tier and the upper tier is bouncing up and down in unison.

There are red and white balloons flying everywhere, this is a proper play-off atmosphere.

It is a great atmosphere from both the Charlton fans and the Wycombe fans.

It's a crackling atmosphere in The Valley tonight - almost back to the days when the home side graced the top flight.

An early Wycombe corner is taken short and Adam Reach's shot is blocked.

Here we go.

Done before closing time or could we go the distance?

We're about to find out...

There are one or two Charlton fans who think it is done and dusted, there is the feeling in the crowd and I have been listening around the ground since 5PM.

I have been wandering around and looking at their fun day event they have got on tonight, with a beer tent.

But I have gone round and I think there are a lot of Charlton fans who think the game is done already.

That is probably a good place for Wycombe to be, with that sort of atmosphere.

Mike Dodds has led Wycombe to seven victories from his 18 games in charge with six defeats.

Victory tonight would leave them one game from a return to the Championship where they spent one season in 2020-21 but they'll have to overcome Charlton and a boisterous atmosphere at The Valley.

"They have a certain style they've played for a consistent period of time so I don't see the style changing but the occasion will be different so we'll have to separate the two," Dodds told BBC Three Counties Radio.

"We've got one of the best away records in the league and we know what the game is going to look like."

Dodds is right about the Chairboys' away record with only the champions, Birmingham (50) taking more points on the road than their 42.

He is wary about their surroundings this evening.

"If we manage the atmosphere and occasion we're an incredibly strong team at this level so we're going into the game really confident and we're going to have to spoil the party," he added.

The Valley is a wonderful place to be and it is such a great stadium. There is so much history here, and it is a night that could go down in history.

It is a game that could get Charlton into a play-off final to play Leyton Orient, which would be huge for London football.

They have got to get past Wycombe and we saw in the first leg they are a tough nut to crack, it was a real struggle.

Charlton can look back at the 2-1 victory here against Wycombe in the season, so they will have that confidence and I think they will be roared on as well.

We have seen recently what this ground is like when it is full and shaking and tonight is going to be one of those occasions and hopefully Charlton can live up to what the fans provide.

The last time Charlton appeared in the League One play-offs they were promoted - beating Sunderland 2-1 in the final in 2019.

They also did the double over Wycombe in the regular season but boss Nathan Jones is taking nothing for granted tonight.

“We know the difficulty of the task but we’ll concentrate on us, on our strengths and what we’re good at and if we turn up and we’re the best versions of ourselves then that’s all I can ask of our players," he told BBC Radio London.

"We’ll prepare the same way. The game doesn’t change - it’s 11 v 11, seven subs, two goals, one ball, officials, it’s just we’re playing home and not away.”

Having seen last night's tie go to a penalty shoot-out, Jones is ready for this one to also go to the wire.

“We will be ready for all eventualities,” he said.

Tonight's sides at least know what's in store should they get through.

Last night Leyton Orient beat Stockport 4-1 on penalties after a 3-3 draw on aggregate to secure their place under the arch.

Ethan Galbraith struck the winning penalty for Orient after goalkeeper Josh Keeley had saved from Hatters winger Jack Diamond and Ryan Rydel struck the post.

"I've got a lot of love for this football club and I want to get to the Championship with Leyton Orient - it would be an unbelievable occasion," boss Richie Wellens told BBC Radio London.

"We're not a Championship club - the stadium isn't big enough, the training ground isn't good enough, we're not a Championship club - but if we get there it will accelerate.

"The new ownership have plans to get there. It means we can maybe keep some of the players that are out of contract or are on loan, so it opens up a lot of doors."

It wasn't exactly fun in the park on Sunday evening as Charlton and Wycombe produced a goalless first leg.

The game saw only five shots on target and got pretty physical on certain occasions.

"Two really good teams cancelled each other out I think," Wycombe boss Mike Dodds told BBC Three Counties Radio.

"When you play a Nathan Jones team they are so aggressive in the first phase we didn't want to give them the momentum in of making too many es in front of them which probably contributed to the fact it was quite messy at times."

Charlton may have the slight advantage by playing at home tonight and head coach Nathan Jones is comfortable with that, as he told BBC Radio London:

"It's evenly poised and it's not a bad place to be. We've got to win a home game to get to Wembley and I think we'd have taken that.

"I'm really proud of the performance because we showed a resilience. Would I have liked us to play a bit more and create a bit more and show a bit more quality? Yes."

Charlton boss Nathan Jones makes two changes for the return leg.

Thierry Small and Alex Gilbert get the nod to start at the expense of Luke Berry who misses out through injury and Tennai Watson who is among the substitutes along with the returning Chuks Aneke and Daniel Kanu.

The big news for Wycombe is a change in goal where Franco Ravizzoli replaces Will Norris who is ill.

Garath McCleary is in for Fred Onyedinma who drops to the bench. Shamal George is the substitute goalkeeper.

It's been another warm week and temperatures are sure to be high at The Valley tonight.

Charlton and Wycombe served up, let's just say an attritional first leg, but something will have to give this evening.

Leyton Orient await the winners in the Wembley final on 25 May but who will they face?

Standby everyone, we're going in...
