In Germany they call it Englische Woche, a tribute of sorts to the Premier League's influence when the Bundesliga hosts a round of midweek fixtures.
Quite fitting, then, that the three big names linked with a transfer to Chelsea in the next transfer window all struggled in their second games in 72 hours.
Following notable, match-defining performances from Jadon Sancho, Kai Havertz and Timo Werner on Saturday and Sunday, all three looked leggy and requiring a second wind during the midweek games.
There is undoubtedly a wider point to be made about the perils of returning to competitive action off the back of such a short period of training, something several Premier League coaches including Frank Lampard have stressed in one of many recent meetings.
But it is also a reminder that every young player has moments of inconsistency. It is part of the development curve and a worthy reminder for those who may have tuned in for a first close-up look at the names linked with their club.
Sancho may have been part of 30 league goals so far this season - 14 goals, 16 assists - but he has not been fit enough to start any of Dortmund's three games since the restart because of a calf strain.
Expecting him to come on at the interval while trailing Bayern Munich 1-0 and turning the game around was just a step too far. But no big deal in the longer scheme of things and unlikely to do much to alter his eye-watering £120million price tag.
Kai Havertz, on the back of four goals in the first two games back, looked starved of supply in Bayer Leverkusen's heavy, shock 4-1 defeat at home to Wolfsburg on Tuesday evening.
Again, not a big deal to have an off-night in attack for a team enduring a bizarre defensive disasterclasss.
And then, to complete the hat-trick, Werner barely had a kick for Leipzig in the 2-2 draw against Hertha Berlin three days after banging in a hat-trick away to Mainz. Hertha, it should be factored in, also had two days extra rest.
It was no coincidence that all three failed to hit their usual levels in such physically taxing circumstances but those harbouring doubts over their abilities, a point more applicable to Havertz and Werner for obvious reasons, must not cast firm judgments without further examinations.
