Training at a stadium belonging to Marine Football Club of the Northern Premier League's Premier Division, the German outfit appear to be in relaxed mood.
But what have they been up to in training? Well, we're pretty sure that they were involved in some sort of reaction drill where they had to throw the ball against the cross bar before attempting to find the back of the net.
It's certainly a bizarre session, but clearly an enjoyable experience. See it here:
Marine chairman Paul Leary has revealed that he thought Dortmund were on the wind up when they asked him to use their facilities.
As per the Liverpool Echo, he stated: "When the e-mail landed from Borussia Dortmund, it was April 1! We got the request asking if they could use our facilities for a training session on the morning of the game, and I had to say 'look, if this is an April Fools' joke then stop now!
“But it's great for the club and the local area, to have these players here. It's been a stressful couple of weeks worrying about the logistics and what not, but I can relax now. They did an hour on the pitch, the full squad, and then off they went.
“I did ask them if they could maybe loan us a couple of players for our next crucial league game, but I had to make do with a signed shirt!”
In all honesty, keeping his players calm ahead of tonight's contest may well be the best route to go down for Dortmund boss Thomas Tuchel.
The clash on Merseyside looks set to be a ferocious one with both teams desperate to secure a place in the semi-final of the competition. After the 1-1 draw in the first leg last week, the tie is nicely poised and should represent a terrific occasion.
Reds chief Jurgen Klopp has insisted that his side must forget last week's clash and concentrate on going into second-leg with the right attitude.
Klopp stated, as per Sky Sports: "I don't think we went to the limit of our performance last week and I don't think Dortmund did either, but they are having a great season.
"Against Dortmund you can't just defend, there is a balance between attack and defence.
"Forget about last week's game, we have to go into the game with a different attitude and we certainly won't be flying a white flag."
