RB Leipzig might need some of the fuel their backers Red Bull provide through their popular energy drink.
The Bundesliga side have had a jam-packed schedule as they chase an historic first major trophy in their history.
And Rangers will be hoping the Germans are running on empty by the time they arrive in east of the country for the first leg of their Europa League semi final on Thursday.
Domenico Tedesco’s side suffered their first defeat in 15 games when they went down to two late goals at home to Union Berlin at the weekend.
Their previous loss came when they went down to 10-in-a-row champions Bayern Munich by the odd goal in five back in February.
It’s been an impressive run but could there be signs of fatigue as they close in history with the German Cup – they take on Freiburg in the Final on May 21 – and the Europa League their two shots at glory.
German journalist Yvonne Gabriel has followed RB Leipzig on every step of their journey in her role covering the club for BILD having attended their first ever training session after their 2009 foundation.
And she gave her thoughts on the latest edition of the Record Rangers podcast ahead of the showdown.
“For me, it seems like the team is tired just now,” she observed. “They have had 44 matches this season and the only German club in three competitions – Bundesliga, German Cup and Europa League.
“They have a big squad but at the weekend and the two previous matches – the German Cup semi final against Union Berlin and league match against Leverkusen – it looks like the team are losing a bit of their power so it will be interesting to see how they perform in the run-in.”
Rangers fans will take hope from the fact they defeated Borussia Dortmund earlier in the competition as they currently sit second in the table with Leipzig fourth.
But she said: “Looking at the table it looks like Dortmund are better than Leipzig but if you take it from when Tedesco arrived in December then Leipzig are better. Leipzig are the form team this year.
“The first half of the season was very difficult they had to change the coach – for only the second time in their history – during the season so it was like a restart in December.
“Jesse Marsch, the American coach, was a big mistake so they changed to Tedesco and after this kind of season it would be crazy to win their first title because nobody expected it.
“When they reached the German Cup Final the CEO Oliver Mintzlaff had tears in his eyes. He said there had been so much pressure and the biggest crisis of the club so far.
“It’s good to have success and get promoted but to have a trophy is something different and that first title for the club would be a source of great pride.”
