When you think about it carefully, it's still bizarre that Mesut Ozil is currently playing for Arsenal.
Throughout the summer there were no serious indications that Real Madrid were prepared to sell the effective Germany international - even after Los Blancos paid a world record £85m fee to sign Gareth Bale.
Angel Di Maria and Karim Benzema were far more likely casualties, yet it was Ozil who was surprisingly allowed to leave when Arsenal approached Real Madrid president Florentino Perez with a £42.4m bid at the end of the summer transfer window.
Cristiano Ronaldo reportedly slammed the decision, while the Real Madrid faithful weren't particularly impressed either. It's easy to understand why.
Ozil undoubtedly falls into the world-class category; he makes things happen on the pitch and possesses the mentality to make a difference in the biggest matches.
These are the reasons why Arsenal boss Arsene Wenger was prepared to spend so much money. The Gunners had never paid close to £20m on a player before, but did not hesitate to spend more than double that figure on the player Sir Alex Ferguson once nicknamed "The Ghost" because of his ability to drift between the lines without being noticed.
Real Madrid, in the panic of desperately trying to recruit some money back from the Bale purchase, ended up parting company with their second best player.
And the Spanish giants' loss has clearly been Arsenal's gain.
The Gunners were already performing reasonably well before Ozil's arrival, but the 24-year-old has given everyone at the Emirates Stadium a huge lift, while he has also been able to showcase his immense quality from the very first minute he pulled on the Arsenal shirt.
Ozil lived up to his other nickname - "the assist king" - by setting up Olivier Giroud in the opening minutes of his Arsenal debut against Sunderland, and then set up three more goals in his first home match against Stoke City.
He's also managed to make an instant impact in the Champions League, effectively killing a decent Napoli side off inside the opening 15 minutes with another assist and a tremendous goal, and if Arsenal can keep him fit for the entire campaign then surely that eight-year trophy drought will finally come to an end.
It's not as if all of their hopes and dreams are pinned entirely on Ozil's shoulders, either. The likes of Jack Wilshere, Aaron Ramsey and Santi Cazorla will compliment the club's record signing perfectly over the course of this and future seasons.
But with Ozil in their ranks, Arsenal can finally dare to dream big.
