As you already know, Arsenal primarily signed Shkodran Mustafi from Valencia for £35 million to solve their defensive crisis and bolster Arsene Wenger's options after a tricky start to the Premier League.
But officials at the Emirates are also hoping that Mustafi's arrival will also have a very positive knock-on effect on another deal they are trying to finalise.
According to The Mirror, the German international's close friendship with Mesut Ozil could help with contract negotiations for the former Real Madrid star.
Ozil still has two years left on his current deal with the club but the Arsenal hierarchy are eager to tie the midfielder down to a longer contract before other teams are given the opportunity to twist his ear.
The report claims the 27-year-old has been reluctant to extend his stay in north London until the club's ambitions have become clearer and match his own personal desire to win major trophies.
The Gunners may have left it late in the day but the additions of Mustafi and Spanish forward Lucas Perez actually took their overall spending for the summer past the £90 million mark.
Only Chelsea, Manchester United and Manchester City spent more than Wenger so it might be fair for Arsenal officials to assume their actions in the transfer market should ease Ozil's concerns.
Now it will be performances on the pitch where Ozil will be looking for improvements, however, signing a close friend of the German has been somewhat of a bonus and could prove the final factor in convincing him to stay.
Ozil has made over 100 appearances in all competitions since moving from Real Madrid for over £40 million in 2013 and can boast a very impressive record of 21 goals and 43 assists during his time in England -hence why Wenger and co. are so desperate to keep him.
While Ozil will undoubtedly play a big role in Mustafi settling into his new environment, it would appear the latter may also have a crucial say in the future of one of Arsenal's most important players.
