David Alaba was presented as a Real Madrid player on Wednesday, and the jersey number the Austrian defender will wear at the club has also been confirmed.
Alaba joined Real Madrid after leaving Bayern Munich at the end of his contract, signing a five-year contract with the Spanish giants.
Alaba will be wearing the no.4 jersey at Real Madrid, previously worn by club legend Sergio Ramos, who joined PSG on a free contract this summer.
Alaba says he knows what the jersey number means to the club, but insisted he is not here to compare himself with others.
"I spoke to the club about that," Alaba said in his introductory press conference, as quoted by Marca.
"They offered me that number. I don't think there was any other.
"I know what the number means for the club and that motivates me. It represents strength and leadership. I want to give my all for that number.
"I haven't come here to compare myself with others. I'm David Alaba and I'll keep being David Alaba. I'll be myself."
Meanwhile, with Ramos having left the club, and Raphael Varane heavily linked with an exit this summer, Alaba will be key for Real Madrid in defence in the next and coming seasons.
