Refere Istvan Kovacs stops play so Brahim Diaz can get treatment. He did a nice bit of skill to get past Stanislav Lobotka, who fouled him.

Diaz is OK but Milan have this free-kick on the right wing. It's whipped in and Alex Meret punches away, not the most convincing.

The first coming together between Wesley Fofana and Vinicius Junior sees the latter beat the former with ease. Fofana clobbers him and gets a deserved booking. Just the 85 minutes to avoid a second.

No player has had more shots in the Champions League this season than Napoli's Khvicha Kvaratskhelia (31).

Kvaratskhelia is only the third Georgian player to play in a Champions League quarter-final, along with Kakha Kaladze (Dynamo Kyiv and AC Milan) and Levan Kobiashvili (Schalke).

Chelsea are forward again on the counter.

This time Joao Felix's low ball from the left is cleared by Real.

Promising early signs for the Blues.

The Chelsea corner from that Joao Felix shot is poor. Real clear and then Chelsea loop a tame ball straight out of play.

That's the game in a nutshell there for Chelsea, though. Stay compact and hit on the break.

Joao Felix just didn't have the pace to get away from Eder Militao.

That was a big moment for Chelsea.

A fourth Napoli chance in four minutes as Giovanni di Lorenzo heads wide from Mario Rui's ball.

The visitors are playing without a recognised striker tonight.

Chance!

Chelsea on the counter. Joao Felix is away, in behind Eder Militao. The Real defender gets back but can't prevent the shot from the on-loan Blues forward. Thibaut Courtois shovels it wide.

Napoli have come out flying in their first ever European Cup quarter-final. Andre-Frank Zambo Anguissa's long-range strike is tipped over the bar by Mike Maignan.

Real waste no time getting on the ball. Rodrygo can't find a way past Mateo Kovacic on the right side of the Blues box.

Napoli almost lead within 50 seconds. Milan fail to deal with a cross and then Rade Krunic passes it straight to Khvicha Kvaratskhelia, but Krunic then blocks the Napoli player's shot on the line. Mario Rui fires the rebound over.

Chelsea with a 3-5-2 setup - a packed midfield full of industry to try and keep Real at bay.

This is some challenge for the Blues.

Two more Champions League quarter-final first legs. They're fascinating ones too.

They are under way. Bring on the drama.

The teams are out at the Bernabeu. Frank Lampard and Carlo Ancelotti share a big hug.

Once we get the anthem out of the way, we'll get this show on the road...

Each of Karim Benzema’s last 10 goals in the Champions League for Real Madrid have been scored against English clubs (that is four against Chelsea, three against Manchester City, and Liverpool) – this is already the longest run of consecutive goals by a player coming against clubs from a single nation. All 10 of those goals have been scored during the knockout rounds.

Chelsea have got experience and they have a World Cup winner in Enzo Fernandez.

The key thing is N'Golo Kante coming back in.

It's important for Chelsea to keep their lines tight because if they get spread and the tactical set up isn't correct then they will get picked apart.

Along with six goals and three assists in eight appearances in the competition this season, Real Madrid’s Vinícius Júnior has completed more dribbles (32) and made more progressive carries (102) than any other winger or forward in the Champions League this term.

Raheem Sterling has scored 27 goals in the Champions League, the second most of any Englishman after Wayne Rooney (30). Sterling has been involved in five open play goal-ending sequences in the competition this season, the most of any Chelsea player.

Chelsea are currently unbeaten in six Champions League matches against the reigning champions (W2 D4) since losing against FC Porto in 2004-05 – this is the longest ever unbeaten run in the competition against the current holders.

Chelsea have only lost one of their seven games against Real Madrid in European competition - indeed, they have the lowest percentage of losses against Real Madrid (14%) of any side to have played them 5+ times in Europe.

The Blues have only lost one of their last nine Champions League knockout stage matches away to Spanish opposition (W3 D5), while they are unbeaten in three such trips (W2 D1).
