Chelsea, though, are getting joy in the opposition penalty area everytime they get forward.

N'Golo Kante picks out Marcos Alonso with a cross-field pass but the Spaniard's side-footed volley is straight at the Lille keeper.

Arnaut Danjuma, who bagged a hat-trick at the weekend, has a backheel shot but it's straight at Wojciech Szczesny.

This was Kai Havertz's third goal in the Champions League, after previously netting the only goal in the 2021 final against Manchester City and in the Blues' 4-0 group stage home win versus Malmo earlier this season.

Romelu Lukaku had seven touches of the ball in 90 minutes v Crystal Palace on Saturday.

Kai Havertz has already had eight touches of the ball after 15 minutes tonight.

Steve in Milan: Seven minutes and Kai has shown three times why we are better without Lukaku.

Trevor Gladwin: Kai Havertz has not got nearly enough minutes this season. Wonderful player.

Lille's corners have caused some angst for Chelsea.

This time Amadou Onana meets Jonathan Bamba's cross but cannot replicate Kai Havertz's effort at the other end and nods wide.

Villarreal's Giovani lo Celso should level but he slices his shot from 10 yards off the outside of the post after good play by Alfonso Pedraza.

Chelsea's fans are in in buoyant mood singing "Champions Of The World" as they celebrate an early lead. It was third time lucky for Kai Havertz, who almost scored twice before he actually did.

Dusan Vlahovic (22 years, 25 days) is the second youngest player to score on their Champions League debut for Juventus after Alessandro del Piero (20 years 308 days).

It is the first time Juventus have scored in the first minute of a Champions League game since October 1997 against Manchester United (Del Piero).

Vlahovic's goal was the earliest goal in a Champions League knockout stage match since David Alaba for Bayern Munich - against Juventus - in April 2013.

Lille are having a decent spell of pressure and it's Jonathan of the Bamba variety who finds room in the box but sees his shot blocked by Thiago Silva.

Jonathan of the David assortment then blazes a shot over the bar from range.

Havertz has started like a house on fire. It's a brilliant delivery, outswinging, Havertz is unmarked six yards out, gets up and he nods it down.

The goalkeeper is fuming as he is unmarked. You can't give him that time and space. Chelsea totally deserved that.

It has been a brilliant start from Chelsea and Lille don't know what has hit them.

Lille get in behind Chelsea's backline for the first time.

Turkey international Zeki Celik finds space down the right but sees his low cross cut out by Thiago Silva.

In the next move, Renato Sanches' delivery almost draws an own goal from Antonio Rudiger, whose sprawling interception sees the ball loop over Edouard Mendy and onto the roof of the net.

Juventus seem to be playing a back five and not a 4-4-2 as the graphics showed earlier. Juan Cuadrado at right wing-back does well to deny Villarreal a corner.

I think they might have started with a back four but then had a lead to defend after 32 seconds...

It's Kai Havertz who is in the thick of the action for Chelsea.

Christian Pulisic plays a nicely weighted pass through to the German, who cuts on to his favoured left foot, before a curling shot is superbly tipped wide by Leo Jardim.

Dusan Vlahovic's goal after 32 seconds is the quickest ever by a Champions League debutant.

Andy Moller took 37 seconds to score against Juve for Borussia Dortmund in September 1995.

Kai Havertz scored winning goals in the Champions League and Club World Cup finals.

That £71m is already paid off, no matter what he does for the rest of his Chelsea career.

Dusan Vlahovic - two touches, two shots. He runs in behind the home defence but has his shot blocked. Corner.

That's a bad miss from Kai Havertz and Chelsea really should lead.

Cesar Azpilicueta plays in a delightful low cross into the six yards box, Germany international Havertz is unmarked but side-foots his first-time shot over the crossbar.

Looked harder to put it over than put it into the back of the net.

Chelsea right on the front foot in the opening minute, with Kai Havertz looking to bundle through but is halted in the box by Sven Botman.

The much talked about Sven Botman.
