Chelsea have a good record against PSG, but with a front three of Zlatan Ibrahimovic, Ezequiel Lavezzi and Edinson Cavani tonight, surely they will cause them a few problems?

"Is it still Valentine's Day? Deary me. Two teams are lining up for a Champions League match but all the players are hugging and kissing each other..."
Well, Paris is the city of love, Phil. Get in the spirit...
The players are in the tunnel, the atmosphere in the ground is fantastic. Champions League football is back and kick-off is moments away. Here is a quick reminder of the line-ups.
PSG: Sirigu, van der Wiel, Marquinhos, Thiago Silva, Maxwell, Verratti, Luiz, Matuidi, Lavezzi, Ibrahimovic, Cavani. Subs: Douchez, Camara, Bahebeck, Digne, Rabiot, Pastore, Kimpembe.
Chelsea: Courtois, Ivanovic, Cahill, Terry, Azpilicueta, Ramires, Matic, Willian, Fabregas, Hazard, Costa. Subs: Cech, Luis, Zouma, Oscar, Drogba, Remy, Cuadrado.
Referee: Cuneyt Cakir (Turkey)
Matthew Smith: Interesting to see Luiz in midfield. I don't think Blanc fancies his chances against Diego Costa!
Rian Hoskins: PSG benefit by using David Luiz in midfield to protect against Costa and Fabregas. The midfield battle is where it will be won.
Eyobel Gomini: I'm surprised Zouma has been left out. Zlatan, Cavani and Lavezzi to outpace Chelsea's defence. Allez Paris-Saint-Germain!

PSG boss Laurent Blanc: "I know Jose Mourinho a bit and I know he'll raise the heat. So my players need to remain cool headed, not react and keep calm."

"Mourinho will be be thinking that with Fabregas, Costa, Willian and Hazard, when they win the ball there's every chance of scoring an away goal. That is what they managed to do here in Paris last season.
"The biggest problem Laurent Blanc has is that the quality of the league PSG play in doesn't prepare them for matches like tonight."
Jose Mourinho did not look a happy chap at all about at having to walk to the Parc des Princes players' entrance after the team bus got stuck in the tunnel entrance.
Not a great start to the evening for the Chelsea boss, but an early goal would certainly put a smile on his face.
The Beast is most certainly in the building..., external
Phil Ecstasy: It will be fun watching Costa and Luiz tonight.
Ram Rimal: Costa will score tonight. Mourinho is making sure Costa will be in beast mode by saying he's not fit.
Frank K Mponda: I predict PSG will snatch it 2-1...

In 2004, a 41-year-old Jose Mourinho stood in the Parc des Princes dugout to take charge of a Champions League game for the very first time as Chelsea boss.
He oversaw a 3-0 win, with Didier Drogba scoring twice. Will history repeat today?
"Amaze us!" implores French newspaper L'Equipe ahead of the game, but the publication highlights the "frightening" statistics, external concerning how French sides fare against English teams. Their win percentage is just 24%.

"PSG can cause Chelsea problems with their strikers, plus they are so strong in midfield. They have great players all over the pitch, but can they play as a team? Is there much cohesion? They are a good team, but are they a team that can go on and win the Champions League?"
Interesting to see that David Luiz is playing centre midfield for Paris St-Germain. His stats in defence for PSG are impressive, will they miss his presence there?
Ryan Webster: Frank Lampard always seemed to score against the Hammers
Andy Tasker: Dreaded Torres coming back to Anfield and scoring. The fear never materialised. Now I'm dreading Luis Suarez getting at us one day.
Shaun: Surely Peter Crouch has to make the list? He's got enough former clubs!
Which ex-player always scores against your club?
Away from the Champions League briefly, there are three games in the Championship tonight with Derby able to go top of the table.
Currently third in the standings, they travel to 20th-place Rotherham where are a win will move them two points above current leaders Bournemouth.
Wigan, meanwhile, will be keen to alleviate their relegation fears with a win tonight, but they face a tough test at Reading while Cardiff, 17th in the table, host a Blackburn side fresh from beating Stoke in the FA Cup at the weekend.
There are five games in League One with the pick of the bunch being leaders Bristol City at home to Peterborough. City are four points clear at the top and victory would strengthen their grip on first place.

"If I was a Chelsea fan I'd prefer Luiz to play at the back and have to face Costa. Playing him in midfield takes him out of the firing line a little bit. I think it's a clever move from Laurent Blanc.
"Cahill brings experience to the Chelsea defence, but I'm surprised Zouma has been left out. He played against Liverpool and Man City. But with Cahill back in it's a really solid-looking back line."
So who will come out on top tonight? There is no doubt that Zlatan Ibrahimovic will be the biggest threat to the Chelsea defence tonight, but his goal-scoring record against English sides is no great shakes.
In 16 games against English opposition, he has scored just three goals...
Speaking of PSG's twitter feed, they have been engaging in some unusual banter prior to the game.
Yesterday they tweeted this picture,, external for example, of Sir Winston Churchill, with the caption: "Hey Chelsea, what if every 'English figure' in Paris was ready for tomorrow?"
