Borussia Monchengladbach had only managed to score 13 goals in their two previous Champions League campaigns combined.
This time around, in a group few people gave them much hope of getting out of, they've netted 14 times - and counting.
Drawn together with the might of Real Madrid and Inter Milan, plus tricky customers and Champions League old hands Shakhtar Donetsk, most predicted third place and the Europa League post-Christmas for Die Fohlen, at best.

It's little wonder their manager Marco Rose is smiling with Gladbach top of Champions League Group B ahead of heavyweights Real Madrid and Inter Milan
With eight points from four matches, Gladbach have left the heavyweights trailing behind
But Marco Rose's side currently top Group B and remain unbeaten after four of their six games. Eight points are already in the bag and their goal difference is a stonking +10, if it came down to it.
Real and especially Inter have been left trailing in their wake, while the German side have made Shakhtar their whipping boys after thumping them 6-0 in Ukraine and 4-0 at the Borussia-Park.
And before anyone speaks of Shakhtar being weak, let's not forget they beat Real 3-2 on matchday one. That fact certainly puts Gladbach's goal rampages into positive perspective.
Prior to that, Rose's team were more than a match for the supposed big guns in the group. They came within seconds of winning in the San Siro before Romelu Lukaku snatched Inter a barely-deserved 2-2 draw.
And they came even closer to victory over Real Madrid before Casemiro made it 2-2 in the third minute of stoppage time.

Monchengladbach need one more win to make sure of their Champions League last-16 place
The Bundesliga side turned Shakhtar into whipping boys by scoring 10 goals over two games
If Borussia had just held their nerve and concentration for a few more moments in both those games, they'd be home and dry.
As it is, a win at home to Inter next Tuesday will take them into the Champions League knockout stages for the first time ever. With Antonio Conte's side flailing, there's every chance Borussia will get the job done before they head to Madrid on matchday six.
The vibrancy of Gladbach's football, especially in attack, will come as no revelation to regular watchers of the Bundesliga.
Rose was brought in to replace Dieter Hecking after the club narrowly missed out on Champions League qualification at the end of 2018-19 and there was an immediate bounce.
