A first attack by Olympiacos as they give their defenders a bit of a rest.

Chiquinho strides forward but puts his cross too close to David Raya.

PSV Eindhoven thought they had taken the lead at Bayer Leverkusen with a back-post header from Ivan Perisic.

However, the former Tottenham winger had strayed just offside and the goal is chalked off.

I'm going early with it, but what a start from Arsenal - it could be a long night for Olympiacos.

This is pretty exhausting for Olympiacos as they are chasing shadows at the moment.

Arsenal look sharp, are playing at a high tempo and are passing the ball around quickly.

A promising attack for Monaco but there just seems to be a bit of miscommunication with two players going for the ball on the edge of the box and they can't make the chance count.

A massive chance for Martinelli who heads wide from six yards out.

Mikel Arteta had his head in his hands when he missed that.

A cloud of smoke hangs over Stade Louis II from the crowd's flares as Phil Foden whips in a dangerous free-kick to the far post but there's no one there to get on the end of it.

Oh Arsenal should be 1-0 up after 90 seconds!

Myles Lewis-Skelly is allowed to run towards the box unchallenged from the left and he then sends a great ball in for a completely unmarked Gabriel Martinelli, but he somehow heads wide six yards from goal.

Huge chance.

News of a late change to the Paris St-Germain XI - and it's another big loss for the visitors.

Joao Neves sustained an injury in the warm-up and Warren Zaire-Emery replaces him in the starting line-up.

Meanwhile, Lamine Yamal is all warmed up already, instantly jinking past a couple of players before playing the ball through to Ferran Torres.

We're under way in the Champions League across the continent.

There's a tribute in the stadium to Billy Vigar, the Chicester City striker and former Arsenal academy graduate who died last week.

Supporters stood and applauded his memory as his picture was shown on the big screen.

Bernardo Silva says he knows what his future holds as he nears the end of his contract.

The 31-year-old's deal expires at the end of the season.

Speaking before leading Manchester City out as captain against his former club Monaco in the Champions League on Wednesday, Silva said: "I know exactly what I'm going to do but it's not the time to focus on it.

"It's to do my best, to put the club back to where it belongs. We've had a lot of captains who've left but it's for the guys who have the most experience to pass it on to the young guys.

"Manchester City was so successful in the last eight years not because one captain was really good but because we have a group of great leaders.

"As the first captain you have to make sure some things don't happen - to create that environment but what we've seen is a group of great characters.

"My job now is to try to create that energy, that chemistry as a group of captains - me, Ruben (Dias), Rodri, Erling (Haaland) - so people behave in the right way."

Both Villarreal and Juventus are looking for their first Champions League win of the campaign tonight at Estadio de la Ceramica.

Villarreal were beaten 1-0 at Tottenham and Juventus looked to be heading for defeat as well, trailing 4-2 at home to Borussia Dortmund with 93 minutes gone.

However, two late goals saw them rescue a dramatic 4-4 draw - and it was an Englishman who scored the 96th-minute equaliser.

Lloyd Kelly joined Juve on loan - with an obligation to buy for £20m - from Newcastle in the summer and has enjoyed two big moments for his new side already.

The defender opened the scoring against Inter Milan just days before heading the remarkable late equaliser against Dortmund.

Can the 26-year-old, who didn't score a Premier League goal in 64 appearances for Newcastle and Bournemouth, make it a hat-trick of crucial goals tonight?

After a draw at Copenhagen on matchday one, Bayer Leverkusen take on PSV Eindhoven tonight at BayArena.

The German side are unbeaten in their past five games in all competitions and will go in as favourites against a PSV side that fell to a 3-1 home defeat by Union Saint-Gilloise in their first match.

Leverkusen have only lost two of their past 11 matches in the league phase of the Champions League with five wins and four draws.

Meanwhile, PSV are trying to avoid back-to-back losses in the group stage for the first time since November 2018, when they were beaten by Tottenham and Barcelona.

A few familiar faces in this Monaco squad.

Former Tottenham and England defender Eric Dier, Ansu Fati - once tipped as the next big thing while at Barcelona before joining Brighton - and former Manchester United midfielder Paul Pogba.

The Frenchman joined Monaco this summer having served an 18-month ban for testing positive for a banned substance while at Juventus. The original ban was for four years but was reduced to 18 months after an appeal.

Monaco then stepped in to offer him a way back to the game but, after such a long period out, Pogba is not yet considered match fit and therefore isn't in the squad this evening.

The club expect him to return to the pitch following the international break.

Borussia Dortmund drew their Champions League opener, but will still be wondering how they failed to beat Juventus last month.

Dortmund held a 4-2 lead deep into second-half injury-time, only to concede twice very late on, including a 96th-minute equaliser as Juventus fought back to snatch a point in a thrilling 4-4 draw.

Nico Kovac's side entertain Athletic Club, who began their Champions League campaign with a 2-0 home loss to Arsenal.

England under-21 captain Jobe Bellingham, the younger brother of Three Lions midfielder Jude, is expected to feature for Dortmund as he has played 11 times for the club since his £27m move from Sunderland in June, although his recent appearances have come as a substitute.

Mikel Arteta's assistant coach Gabriel Heinze is going through drills with the back four.

One defender takes on another and the coach is making sure they do it with a lot of intensity.
