Dortmund were runners up to rivals Bayern at Wembley in 2013, and won the Champions League in 1997.

Monaco reached the final in 2004 but ran into Jose Mourinho's Porto.

Could either side go all the way again?

Maryhill midfielder Gavin Stokes scored what is one of the fastest goals in world football when he netted from the kick-off against Clydebank.

Stokes' drive from the halfway line took 3.2 seconds to fly past the Clydebank goalkeeper in Saturday's 3-0 win in the West of Scotland Super League First Division, part of the Scottish semi-professional junior football set-up.

All of the Dortmund players have warmed up in shirts showing the face of injured defender Marc Bartra.

The Spaniard had surgery on his fractured wrist overnight and thankfully doesn't seem to be too seriously injured. We wish him a speedy recovery.

Putting the events of the last 24 hours to one side momentarily, who are favourites tonight then?

Monaco are top of Ligue 1 and have an incredible scoring record this season, hitting the net 128 times in all competitions. They were brilliant to watch in both legs of their 6-6 away goals win over Manchester City last time out.

Dortmund are off the pace in the Bundesliga, down in fourth after being whacked 4-1 by Bayern Munich at the weekend.

But they do pack a goal punch of their own - Pierre-Emerick Aubameyang has scored 32 times this year, including a hat-trick against Benfica in the last Champions League game at home.

It sounds like a slightly subdued atmosphere inside the cavernous Westfalenstadion, though the earlier kick-off time won't help on that front.

Dortmund could switch to a back four without the injured Marc Bartra, we shall see.

"We want to show that terror and hatred can never dictate our actions," Dortmund chief executive Hans-Joachim Watzke said earlier on.

Security will be stepped up, the atmosphere could well be dulled and confused, the intensity of the game itself is likely to be affected.

"This is perhaps the most difficult situation that we have faced in the past decades," Watzke added.

Watzke said he he had spoken to players in the dressing room, urging them "to show society that we do not bend before terror".

Despite the apparent claim of an Islamist motive, the attack does not have much in common with previous such attacks, says the BBC's correspondent in Berlin, Damien McGuinness.

The explosives were not designed to cause maximum damage in a crowd - or to target the stadium itself, which is several kilometres away.

Both left-wing and right-wing extremists could also be to blame.

Borussia Dortmund president Reinhard Rauball says the "only positive" to come out of Tuesday's attack was that Monaco fans showed "solidarity" in singing Dortmund's name.  

Yesterday's unfortunate and unwelcome events in Dortmund mean that there are three games to enjoy tonight. Get set for this lot:

Borussia Dortmund v Monaco (17:45 BST)

Atletico Madrid v Leicester (19:45 BST)

Bayern Munich v Real Madrid (19:45 BST)

The hashtag that keeps on giving. Mind you, if you were to pick some fans to put for a night in the hope for a foreign exchange at some point, you could do worse than picking Monaco.

'You can sleep on the floor in the kitchen mate, no problem.'

'You must come and stay on one of our yachts.'

Do we have any readers who are out in Dortmund for the game? I was over there myself for the last game against Benfica.

We'd love to hear from you if you are. You can tweet us at #bbcfootball
