Barcelona vs PSG (agg 3-2) - Champions League quarter-final: Live score, team news and updates as Kylian Mbappe and company look to overturn first-leg deficit plus updates from Borussia Dortmund vs Atletico Madrid

The fans are starting to flock in at Signal Iduna Park.

We know what noise the 'yellow wall' can make when it's having its best day, it will need to be like that today.

I also spot a Jude Bellingham shirt in there, if only he was still a Dortmund player, they could do with a midfielder like him tonight.

Sebastien Haller loves the Champions League.

I'm about to share a statistic that shocked me and will probably surprise all of you as well.

Haller's 12 goals in just 13 appearances in the Champions League - 11 for Ajax and one for Dortmund - means he averages a goal every 72 minutes in the competition.

His minutes-per-goal rate is the best in the history of UEFA’s premier competition among anyone to have scored at least five times.

Barcelona have arrived at the stadium earlier than normal.

It's a huge night for them, especially after how poorly they started the season.

If they manage to win tonight, they will look like one of the more likely sides to win the competition.

Tonight will not be easy, though!

Kylian Mbappe may not have had his best game in the first leg but count him out at your own peril.

The French superstar loves an away day in Europe, especially in the knockout stages. He has scored 13 goals in 11 away games in the Champions League knockouts.

That record has only been bettered by two players, Cristiano Ronaldo with 23 in 39 matches and Karim Benzema with 14 in 34.

How PSG could do with him extending that record tonight.

It's not only the Barcelona fans making noise.

The PSG supporters are making their way to the Olympic Stadium in numbers, and well, they are not doing it quietly.

Seeing the atmosphere like this already is making me extremely excited for tonight.

I can't wait for it to get going!

Last week may have been Raphinha's best performance in a Barcelona shirt.

The former Leeds winger ripped apart PSG at times and his second goal was simply special.

PSG will certainly be wary of him tonight, he could take the game away from them in an instant.

He looks ready for business.

Edin Terzic, Borussia Dortmund boss, speaking on Monday:

Diego Simeone, Atletico Madrid manager, speaking on Monday:

The Champions League really did serve us up some belters last week.

I’m once again feeling reminiscent, so let’s rewind to last week’s first leg between Atletico Madrid and Borussia Dortmund.

Diego Simeone’s side could not have hoped for a better start, racing into a two-goal lead in the first-half thanks to Rodrigo De Paul and Samuel Lino.

Their dominance didn’t last though and Dortmund came back strong in the second period, getting their reward when substitute Sebastian Haller halved the deficit with a fine finish.

The visitors then huffed and puffed in search of a late equaliser, but they couldn't find it. They’ll be hoping that it comes early on tonight instead.

Once again, a tightly contested first leg means tonight could be tense.

Luis Enrique, PSG boss, speaking on Monday:

What a game we were treated to last week!

It was a match that struggled to get going, but it burst into life in the second half, swinging one way and then the other.

PSG’s backline really struggled in the first half, especially Gianluigi Donnarumma in goal, and his mistake allowed Raphinha to send Barcelona into the lead.

However, PSG came out in the second period like a team with a point to prove and overturned Barcelona’s half-time lead within five minutes of the second half.

At that point, it seemed like Xavi's side looked down and out but after some smart substitutions and sheer determination, they turned it back around with Raphinha netting a second and Andres Christensen heading in the winner.

I hope they serve up another thriller tonight!

Xavi, Barcelona boss, speaking on Monday:

Wow, Barcelona is already rocking.

We are still over 90 minutes away from kick-off, but the Barcelona fans are already at the stadium in their thousands to welcome their team.

If this is anything to go by, the atmosphere in the Olympic Stadium is going to be intimidating tonight.

The Catalonians are well up for the fight!

While Atletico Madrid are ahead in the tie, it feels like they may have a tougher time holding onto their lead than Barcelona.

Diego Simeone’s side were comfortable with a 2-0 lead last week at the Wanda Metropolitano, but Sebastian Haller’s late strike changes things slightly.

Borussia Dortmund will feel that with their home crowd behind them, they can turn the tie around. When the yellow wall are on it, Signal Iduna Park becomes a cauldron of noise.

Both Dortmund and Atletico are desperate to reach their first semi-finals in 11 years and seven, respectfully.

This one is tough to call.

If tonight’s match between Barcelona and PSG is anything like last week, we are in for a treat.

Xavi’s side come into tonight with a slender one-goal lead after their comeback in Paris last week and are on a 13-match unbeaten streak since the Spaniard announced he was leaving the club in the summer.

The five-time winners last reached the semi-finals in 2018-19, where they met Liverpool – we all know what happened there – and look set to make the last four.

However, it’s not going to be easy. PSG showed their strength at times last week and still have the potent Kylian Mbappe, who surely won’t perform as poorly as he did last week.

I’m envisioning more goals in this tie, these two always serve up a cracker.

Has it been a week already?

The road to London is really starting to heat up, it will be the end of the line for two teams in the Champions League tonight, but which ones.

Barcelona simply have to avoid defeat tonight to make their first Champions League semi-final in five years, their comeback win in Paris has them in a strong position to knock the French champions out.

The Catalonians are not the only Spanish side who have one foot in the semi-finals, Atletico Madrid travel to Borussia Dortmund with a one-goal advantage.

With both ties so tightly contested, it’s set to be another action-packed night of European football’s premier competition.

Strap yourselves in, it’s time to get going.
