Arsenal are reported to have been informed in early August that Gareth Bale had agreed in principle a transfer to Real Madrid, which alerted Arsene Wenger to the likelihood that a prominent player would be sold by the Spanish club.
Bale's protracted move to the Santiago Bernabeu from Tottenham was finally completed just a day before the close of the summer transfer window, and allowed the Gunners to push through a move for Mesut Özil.
Arsenal had to wait until the world record €100 million transfer of Bale was completed before they could close their deal for Özil but, given the information they had received earlier in the window, Wenger was able to set-up a deal for the German a week previous.
According to Goal.com, with Wenger aware that Real Madrid would have to sell in order to cut costs following the agreement with Spurs, the Arsenal manager made a move for both Angel di Maria and Özil.
While the bid for Di Maria failed, Wenger pushed hard to clinch the signature of Özil and had the 25-year-old over to his house in the week before the transfer deadline in order to convince him to sign for Arsenal.
Wenger has since claimed that Özil took 24 hours to make the decision to move to the Emirates Stadium, and the Gunners were able to announce his €50 million arrival on September 2, transfer deadline day.
