Couple of early set pieces for Barcelona to defend as the home side win a free-kick then a corner but both are cleared with ease.

Away we go in Paris and in Madrid.

All eyes on the two strikers at each end of the pitch this evening with PSG's Kylian Mbappe and Barcelona's Robert Lewandowski both starting.

Mbappe has scored 39 goals in 40 games across all competitions this season for the Ligue 1 champions.

Lewandowski has 20 goals in 40 games, but could his experience shine through tonight?

Borussia Dortmund boss Edin Terzic, speaking to TNT Sports: "It's a great stadium, a great stage. We want to show our best performance.

"The physical ability of Felix Nmecha is very much needed today. He played a really good game in the group against Newcastle.

"All players in the yellow shirt have a great job to do. The margin for error is very small. We know the energy the crowd can create here. If you perform as a team then it's difficult to play us."

Borussia Dortmund's Champions League win in 1997 is the only triumph between these two great clubs, but should there have been more?

Atletico Madrid were minutes away from securing their first European crown but a 93rd minute Sergio Ramos goal secured extra time for rivals Real and the rest is history.

Atletico have taken home the silver medal three times with Dortmund doing so in 2013.

Jurgen Klopp's side were beaten 2-1 thanks to a late Arjen Robben for Bayern Munich.

Will fortunes change this season?

Jadon Sancho is on a mission to reignite his career and a Champions League quarter-final is a great stage to do so.

After moving back to Borussia Dortmund on loan from Man United in January, Sancho has gone on to make 10 starts - scoring twice and assisting once.

Can Sancho fire Dortmund into an advantage ahead of the second leg?

Paris St-Germain’s heaviest ever defeat in the Champions League was inflicted by Barcelona (6-1 at the Camp Nou in March 2017).

That result eliminated them in the last-16, despite having led 4-0 from the first leg.

Coincidentally, Barcelona were managed by current PSG boss Luis Enrique in that historic comeback, which remains the only time a team has progressed from a two-legged knockout stage tie in the European Cup/Champions League after losing the first leg by more than four goals.

Atletico Madrid forward Antoine Griezmann has been in the goals this season in the Champions League with six goals to his name.

The Frenchman makes Diego Simeone's side tick when on the attack and Borussia Dortmund will be more than aware of his talents.

A goal tonight will put Griezmann level with Bayern Munich's Harry Kane at the top of the socring charts with seven.

So, Borussia Dortmund made it to the last eight with relative ease after beating PSV 3-1 on aggregate thanks to goals from Donyell Malen, Jadon Sancho and Marco Reus.

Atletico Madrid, on the other hand, made it through by the skin of their teeth after overcoming Serie A runaway leaders Inter Milan on penalties with the two sides unable to be split after 210 minutes of action.

Are we in for more drama tonight?

Five-time champions Barcelona have certainly not been at their world-beating best in recent years and this is their first appearance at this stage of the Champions League in four years.

But boss Xavi thinks his side are in a good moment.

"It is a key moment. The word after being out of the quarter-finals for four years is excitement," said Xavi.

"We can dream again. We think we are at the best moment of the season, but we have one of the best teams in Europe in front of us, with one of the best coaches in Luis Enrique. It is a team built to win the Champions League."

Xaxi added that he had a "great relationship" with Luis Enrique and the club can be proud of the "Barca DNA" that he shares with Manchester City boss Pep Guardiola and Arsenal manager Mikel Arteta.

"From here on it's up to the players to find the DNA that identifies us so much," said Xavi.

"Football is unpredictable but we'll try to control the variations. Luis Enrique has a wide range of talent at his disposal but we'll try to play them [PSG] as equals."

Atletico Madrid boss Diego Simeone has labelled Borussia Dortmund as the "hardest opponent".

The German side haven't lost an away game in four months and are coming to the Wanda Metropolitano looking for a positive result tonight.

"They have a lot of good qualities," said Simeone.

"They are the hardest opponent. They've not lost away from home in four months, and they are great on the counter-attack.

"They are very strong in both boxes, and they are the most intense team in the last eight of the competition."

Paris St-Germain boss Luis Enrique is no stranger to his opponents this evening having won a number of trophies with Barcelona as both a player and a manager.

Most notably, the Spaniard guided the Catalan club to the Treble in 2015 and will be hoping to achieve something similar with his Ligue 1 outfit this year.

But, he says he represents the values of Barcelona better than their current manager Xavi.

"I represent the Barca way better, although others may have different opinions," said Enrique on Tuesday.

"Just look at all the stats and the trophies won."

Well, Xavi did win more than 20 major trophies as a player at Barcelona and La Liga in his first full season as manager last year. Nothing to be sniffed at.

Arsenal's Champions League hopes were left hanging in the balance after they fought out a draw with Bayern Munich at Emirates Stadium.

Bukayo Saka opened the scoring after just 12 minutes but Bayern belied their poor Bundesliga form to turn the game around and Serge Gnabry equalised just six minutes later.

Tottenham's record goal scorer Harry Kane marked his return to north London with a goal as he silenced the hostile Arsenal crowd when he scored from the spot to put the German champions ahead after 32 minutes.

Substitute Leandro Trossard equalised with around 20 minutes of the match to go.

The Gunners thought they should've had a penalty in the dying moments of the match after Bayern were also controversially denied a spot-kick, but in the end it was honours even before the second leg in Germany next week.

It's all to play for.

Madrid certainly didn't disappoint last night and hopefully we get to witness more of the same tonight!

Real Madrid and Manchester City drew 3-3 in a spectacular match at the Santiago Bernabeu with City taking the lead inside three minutes before two quick-fire Madrid goals pegged the defending champions back.

City dominated much of the second period with Phil Foden and Josko Gvardiol both scoring stunners before Fede Valverde responded with one of his own.

At three goals each, the match at the Etihad next week is very evenly poised.
