The confidence of Gunners boss Arsene Wenger proved vital in Ozil's £43million deadline-day switch, after it became clear he no longer was central to the plans of Real Madrid manager Carlo Ancelotti following their world-record signing of Gareth Bale from Tottenham.
It was, though, a decision which left many of the 24-year-old's former team-mates at the Bernabeu stunned, such is the high regard in which Ozil is held among his peers.
Madrid's loss, however, is Arsenal's gain and Cazorla cannot wait to link up with Ozil, who could make his Premier League bow at Sunderland on Saturday.
In an interview with Spanish newspaper Marca, Cazorla said: "I am very happy that Ozil is here. He is a spectacular player and we are very lucky (that) we are going to learn alongside him.
"I don't understand that (why Real Madrid sold him), (because) he is a unique player.
"You will have to ask the club for reasons why they sold them, but at the same time he didn't think he was getting the opportunities he deserved and luckily he has come to us.
"He is an important player and he is going to be very good for the team and the way we play. I hope he can help us fight against the big teams in the Premier League."
Creative talent Cazorla has impressed since his move from Malaga in the summer of 2011, and was reported to have attracted interest from Atletico Madrid.
However, the 28-year-old maintains it was never something on his mind. He added in the Spanish newspaper: "The Atletico president said there was nothing in this, and I always very relaxed about it."
