Mesut Ozil has explained that his feeling he had lost the trust of Real Madrid paved the way for his £42.5 million transfer to Arsenal.
Ozil, 24, completed his switch to the Gunners on transfer deadline day, reportedly signing a five-year contract at Emirates Stadium.
The Germany international said last week he intended to remain at the Bernabeu, but, speaking while on international duty this week, has now revealed his motives for moving to the Premier League.
"At that time [the press conference on Wednesday], I was convinced I'd stay at Real Madrid," Ozil told dfb.tv.
"I soon realised the coach [Carlo Ancelotti] and those responsible no longer placed trust in me. I am player who needs trust and I felt that at Arsenal. That's why I made the switch."
Ozil reserved praise for his new manager Arsene Wenger, revealing a phone conversation convinced him to sign for the Gunners.
He said: "We had a long chat on the phone and he told me about his plans. He trusts me and that's what I need as a player."
"Arsene Wenger places his trust in me and I can further myself. I want to be 100% fit for the World Cup.
"I know what potential I have and I would have come on top at every club in the world, I know that because I am convinced of myself. I am just looking forward to the new challenge and the new coach. I am also looking forward to Premier League."
Ozil, who will link up with German compatriots Lukas Podolski and Per Mertesacker at Arsenal, added: "I am looking forward to my new team-mates.
"I have already heard about their fantastic fans, the city is great, the team is super class and I am just looking forward to it."
Ozil's former Real team-mate Sergio Ramos lamented his departure from the Bernabeu, insisting he would not have let the Germany international go if he were in charge.
"It is clear that he is a team-mate and a friend," Ramos said. "I have always had a 'feeling' with him, and it is a pity. He is a great footballer, unique. It does not bother me, but it is a pity.
"These are personal things, he decides his own future. Every one decides the best and is free to do what they wish. If I made the decisions at Madrid, he would be among the last to leave. But he has decided, and the club too. We have a great team, and I hope this is a great year."
