Due to his performances in the 2010 FIFA World Cup, Özil ensured his place among Europe's top young talents. He was sought by teams like Barcelona, Arsenal and Real Madrid. English striker Wayne Rooney was one of the many admirers Özil had garnered with his performances in the World Cup, and had even asked Manchester United manager Sir Alex Ferguson to sign the German playmaker. There were reports claiming that a deal was struck for a transfer to Barcelona, but Werder Bremen denied the reports and on 17 August 2010, the team announced that they had reached an agreement with Real Madrid for Özil's transfer. The transfer fee is believed to have been in the region of €15 million. Upon signing, Özil said, "When the offer came in to join Real Madrid, there is no decision to make. Let's be honest – you don't refuse this club. I was in no rush to leave Werder Bremen, but this is one club you say yes to. They are an institution, a club with a fantastic history, stadium and squad full of world-class players. The prospect of performing at the Bernabéu is so awesome you jump straight in. " Özil made his debut on 22 August in a friendly match against Hércules, which Real Madrid won 3–1. His jersey numbers were changed often before the season started. He was given the number 26 in the pre-season and 19 for his debut. But following the transfer of Rafael van der Vaart to Tottenham Hotspur, he was given the vacant 23.
