Mesut Özil can do more for Arsenal than boost the side's key passes per game average, to number of assists - he can be the catalyst for a new Arsenal dominion in the Premier League under Arsene Wenger.
The Gunners manager should capitalise further on the circumstances that saw him convince the Germany international that the place for him to thrive best is at Emirates Stadium. Wenger's multi-lingual skills were, according to Özil, key in helping to sell the club.
Being able to describe his prospective importance to the team, should he sign for Arsenal, in Özil's native tongue must not be underestimated - the Frenchman now has a chance to do similarly with other top German stars.
Lukas Podolski and Per Mertesacker have settled in at Arsenal nicely and they, along with youngster Serge Gnabry and Thomas Eisfeld, should help the former Real Madrid star feel at home.
Germany is producing talented youngsters at an astonishing rate these days and Joachim Löw's national team are one of the strongest around, playing some incredibly attractive football - something Özil is key in.
Wenger would do well to work hard to improve the ratio of Germans in his squad and he is a man that knows what benefits can be garnered by having a number of players from a certain nation combining with a British core.
Arsenal's success in his early years was down to lots of things, but his knowledge of the French league's was a big part of this; signings like Patrick Vieira, Emmanuel Petit and Nicolas Anelka made the north London club one of the most feared in the Premier League during those first couple of years.
Latterly, Thierry Henry and Robert Pires came in to repeat Arsenal's double triumph and were crucial to the incredible 'Invincibles' year.
The French contingent at Highbury combined brilliantly with a revitalised British core and produced some of the finest football around, but also had the physical presence not to be bullied against more aggressive opponents.
Özil, Podolski and Mertesacker could start something similar at the Emirates, though this time Arsenal's spending power would not mean Wenger has to spot bargain gems and can compete for the more expensive talent on offer.
That is why the Gunners' new £42.4million man is so crucial; it i more than just producing on the pitch. Wenger must be able to say in future negotiations that Arsenal is a club that has a track record for bringing the best out of German players that join.
Parallels are not only found in the success of French players under Wenger, but with the first few years at the new stadium; Arsenal convinced a number of the best young players around Britain to choose them over Premier League rivals because of their reputation for giving developing players a chance to perform at the highest level.
With reported bids for Bayer Leverkusen's athletic defensive midfielder Lars Bender and interest in exciting young Schalke 04 star Julian Draxler, it could be that Wenger already has that in mind. Ganz Toll.
