Patience Is Key But Chelsea Will Soon Need More From Timo Werner & Kai Havertz

From Bach, to BMW, to beer - Germany has been the origin of so many beautiful and brilliant things. It is a country known for its efficiency, its power, and its no-nonsense approach to, well, anything.

But Chelsea's own injection of German firepower has so far failed to live up to the very high expectations at Stamford Bridge. Kai Havertz and Timo Werner arrived in the summer transfer window for a combined fee of around £117m, understandably sparking fervent excitement in west London.

However, since promising starts to life at Chelsea, things have gone downhill for the duo. Werner is without a goal in his last eight appearances, and Havertz hasn't found the net for 11 games. Both players have just two assists in that time as well. The most recent of those games was a 2-1 loss away at Wolves on Tuesday night where both started - a dismal display from the German pair.

So, after such optimism and hype around the two signings, what's gone wrong?

Werner had bagged himself four goals in four league matches before embarking on his current drought, and doesn't look the same player that had just started to pick up form in a Chelsea shirt. If we look at the former RB Leipzig man's best performance to date for Chelsea - in a 3-3 draw against Southampton - we can see that he played up top in that game.

The striker, from a central position, scored two goals from three attempts and assisted the other, finishing the match with a pass accuracy of 92% - all from just 34 touches on the ball.

But at the moment, neither summer signing are setting Chelsea alight and have shown very little of late. Many in the wonderful world of 'Football Twitter' have labelled them 'frauds' - the title that so many fans love to brand struggling players and managers with.

The Blues visibly lacked creativity in midfield on Tuesday, and it seems Ziyech could prove the most valuable signing to the club in the short-team at least. The Moroccan undoubtedly possesses an ability to unblock avenues and create for his teammates - something that Havertz just couldn't do against Wolves, and ultimately cost the side.

Chelsea were fortunate to have Pulisic back from injury for the game at Molineux. The American was the only creative spark in the final third for Chelsea (in the first half anyway) and, unlike Werner, looked capable of forging something from wide and affecting the game.

Indeed, the return of Ziyech from injury could ultimately see the pair play in their more natural positions, especially if the goals dry up for Giroud.

While they may not turn out to be as big as Bach, BMW, or beer, these boys in blue evidently have the talent to become marquee signings for Chelsea. It is now clear that they will need the precious commodity of time and patience reach something near their best. Whether they will be afforded that remains to be seen.
