A Champions League debut for Brendan Rodgers tonight and an assured start as he chucks in a nice twist to the 'no easy games at this level' cliche there. The teams are in the tunnel - here we go...
Liverpool boss Brendan Rodgers: "Our mindset is to get three points. All games at this level are very difficult. We are looking to put on a performance as well, the boys are really looking forward to it."
Atletico Madrid players have been out on the pitch at the Karaiskakis Stadium ahead of their Champions League Group A opener against Olympiakos.
Arda Turan came off the bench to score the winner in the 2-1 derby victory over Real Madrid at the weekend, and that has earned him a place in the starting line-up tonight.
Olympiakos have one of Fulham's finest ever signings, Kostas Mitroglou, in their side.
Action in Scotland tonight too, as Inverness take on Rangers in a League Cup second round tie.
If the Champions League's not doing it for you, head to Ibrox courtesy of Keir Murray here. He's already mentioned beef-flavoured drinks. He's on form.
What is success for Liverpool in the Champions League this season then? You'd make them second favourites in Group B so they could follow Real Madrid into the last 16. After that - who knows...
Borussia Dortmund: Weidenfeller, Durm, Subotic, Papastathopoulos, Schmelzer, Aubameyang, Bender, Kehl, Grosskreutz, Mkhitaryan, Immobile. Subs: Langerak, Kagawa, Jojic, Ramos, Ginter, Bandowski, Amini.
Arsenal: Szczesny, Bellerin, Mertesacker, Koscielny, Gibbs, Arteta, Sanchez, Ramsey, Wilshere, Ozil, Welbeck. Subs: Ospina, Rosicky, Podolski, Oxlade-Chamberlain, Cazorla, Chambers, Campbell.
Referee: Olegario Benquerenca (Portugal)
Liverpool: Mignolet, Manquillo, Lovren, Sakho, Moreno, Gerrard, Henderson, Lallana, Coutinho, Sterling, Balotelli. Subs: Brad Jones, Jose Enrique, Toure, Lambert, Lucas, Borini, Suso.
Ludogorets: Borjan, Junior Caicara, Moti, Aleksandar Aleksandrov, Minev, Mihail Aleksandrov, Dyakov, Abel, Misidjan, Marcelinho, Bezjak. Subs: Gospodinov, Fabio Espinho, Angulo, Dani Abalo, Zlatinski, Wanderson, Younes.
Referee: Matej Jug (Slovenia)
It's not just Razgrad who are excited tonight though - Liverpool skipper Steven Gerrard says he has been jealous of watching Manchester United and Chelsea compete in the Champions League during Liverpool's five-year absence.
"There has almost been a jealousy and an envy that we weren't involved," said Gerrard, who won the competition with the Reds in 2005.
"I've been craving it. Everyone is looking forward to hearing that music."
Ah, the Champions League anthem. A classic. I'm trying to persuade my better half to have that at our wedding at the moment...
See - everyone loves Jurgen Klopp.
Daily Mirror football correspondent John Cross: , externalWenger and Klopp shared something of a love-in at press conference yesterday. Mutual respect obvious. Klopp says Arsenal have moved up a level this season.
Henrik, a Liverpool fan in London: Over the summer Brendan Rodgers has taken Liverpool from having an excellent first team to a deeper squad capable of replicating the attacking flair we all came to love last season across all competitions, most of all the Champions League. Bring it on!
Sheelagh: Liverpool will not make it past the last-16. How do I know, I hear you ask? Mignolet, Manquillo, Lovern, Sahko and Moreno is how I know. That defence is not of Champions League latter-stage quality, and will be found out by Europe's big guns.
Well, this game's all about opinions...
Liverpool have only won two of their last eight Champions League games - both were against Hungarian side Debrecen.
No Radamel Falcao, no problem? There is a big striker-shaped hole at Monaco following the departure of Colombia international Falcao to Manchester United, so the goal-scoring responsibilities very much rest on Dimitar Berbatov's shoulders.
The big man starts for Monaco, who are back in the Champions League for the first time since 2006, against Bayer Leverkusen tonight.
Just 20 minutes to go until kick-off across Europe and England then.
Whether you're at the Westfalenstadion, Anfield, Deepdale or Field Mill I wish you joy, goals and contentment.

"It's nice that Liverpool are back in the Champions League, but I think the league is more important for them. They'll get out of the group, but I think that's as far as they'll go."
BBC Radio 5 live football producer Phil Wye:, external The sun has set behind the stand at Signal Iduna Park aka Westfalenstadion. One of Europe's finest and most vibrant venues.
Tom Castle:, external This is the most difficult group stage match for Arsenal. The easiest for Liverpool. No pressure for the Gunners, but imperative for the Reds.
Robert Winscott:, external Media up in arms about Bellerin starting, but why? He looked good pre-season. Slight baptism of fire but you have to start somewhere!
Hani Nyabam:, external All need to calm down. Hector Bellerin is the real deal. Watched him in the under-21s this year, and he is the second coming of Jordi Alba.
Mesut Ozil may be scapegoat number one, but is there anyone out there who does not like Jurgen Klopp? I refuse to believe it.
As Steve A said rather brilliantly on Twitter today,, external the Dortmund manager 'looks like a hedge that's been dragged through a man backwards."
Wonderfully done.
One more picture? Yeah, go on then:
What has World Cup winning playmaker Mesut Ozil ever done for us?
