How have other German players at Chelsea fared?
Antonio Rudiger signing for the Blues means he is set to become the fifth of German players at Chelsea to turn out at Stamford Bridge in the Premier League era.
That got FootyOn writers thinking about how the other four got on in West London and whether there are any lessons for Rudiger?
He comes to Chelsea for a reported initial £29,000,000 buoyant after helping World Cup holders Germany win the Confederations Cup.
Rudiger’s part in that success, coupled with a fine upcoming campaign at the Bridge, could well put him in contention to play at the 2018 finals in Russia.
Were the other German players at Chelsea in the Premier League era hit or miss, though?
Judge Ballack on trophy haul
Michael Ballack was part of an all-star Blues midfield that included awesome anchorman Claude Makelele, box-to-box talent Michael Essien and goal-machine Frank Lampard.
While he wasn’t as prolific as when at Bayern Munich and clearly in Lampard’s shadow, Ballack won five major trophies in his four seasons with Chelsea from 2006/07.
His honours include a Premier League and FA Cup double in 2009/10 under Carlo Ancelotti.
Based on winning everything there is at the top of the domestic English game – you can add in the League Cup and Community Shield – Ballack has to be a hit.
Huth hints at what could happen
The most salient comparison when it comes to German players at Chelsea and the arriving Rudiger is fellow defender Robert Huth.
While he would go on to win the Premier League title for a third time against all odds with Leicester City, Huth was a bit-part player in the back-to-back crowns lifted at the Bridge when Jose Mourinho first arrived in England.
There is one key difference between Rudiger and Huth, however; the former has already played senior football abroad with Serie A side Roma.
Huth came to Chelsea as a teenager, but failed to get a regular place, so counts as a miss. He also played for Middlesbrough and Stoke City in the Premier League before joining the Foxes.
Rudiger is far more likely to get into Conte’s plans because both Blues skipper John Terry and Nathan Ake have left the Bridge this summer.
Chelsea also play with a three-man defence, with Rudiger signing perhaps with an eye on the right-sided centre back role.
Marin a total miss
Marko Marin was a highly-rated attacking option when the Blues bought him from Werder Bremen in the summer of 2012, but scored just once in 16 games.
That led to him being farmed out on loan to Spain’s La Liga with Sevilla, then Italy with Fiorentina, the Belgian top-flight next at Anderlecht and Turkish Super Lig side Trabzonspor.
Marin’s Chelsea nightmare finally ended when he joined Greek giants Olympiakos on a permanent deal last summer, but he serves as a cautionary tale for Rudiger.
The Blues’ new arrival has to take his chances when given them.
Schurrle success only as impact sub
And finally, the last of the German players at Chelsea from the Premier League era, Andre Schurrle.
Largely playing out wide, his league return of 11 goals in 44 games includes a West London derby hat-trick against neighbours Fulham.
It sounds like a very unkind thing to say, but Schurrle’s time at the Blues is often viewed as being a short-lived equivalent of Manchester United super-sub Ole Gunnar Solskajer.
Germany have used Schurrle to make an impact off the bench to good effect too, though he also boasts a Premier League and League Cup double during Mourinho’s second spell on his CV.
