The 24-year-old Germany international midfielder completed a club-record transfer from Real Madrid late on deadline day for a fee believed to be £42.5million as Gunners boss Arsene Wenger finally delivered a marquee signing.
The departure of the third-generation Turkish-German play-maker was greeted with shock by some of his former team-mates, so highly is he rated among his peers.
Ozil made his mind up to leave after being told he no longer figured in the first-team plans of Madrid manager Carlo Ancelotti following the world-record signing of Gareth Bale from Tottenham.
The German is now determined to make a major impact with the Gunners alongside the likes of Jack Wilshere, Theo Walcott and Santi Cazorla as the team look to deliver some silverware to finally follow the 2005 FA Cup into the Emirates Stadium trophy cabinet.
"I want to improve myself further and I am looking forward to the style of play. Arsenal are well known for the strength of their technical game and their desire to play attacking football. I think I will fit perfectly into that. That is why I chose to sign for the club," Ozil said in an interview with Arsenal Player.
"In the last few years, Arsenal haven't been so successful, but we want to become more successful.
"We want to win trophies. I think the fans are looking forward to that too.
"We have a very strong and a very young team that can improve a lot under the manager. I think we will win trophies because we have the potential [to do so]."
The influence of Wenger cannot be underestimated in securing a deal which was brokered over the weekend, when Arsenal beat arch-rivals Tottenham in the north London derby.
