Arsenal on Monday announced that they have signed Germany international midfielder Mesut Ozil from Real Madrid for a club-record fee.
"German international midfielder Mesut Ozil has joined Arsenal on a long-term contract in a club-record deal," read a statement on the Arsenal website.
"Ozil, 24, joins Arsenal from Real Madrid, where he made a total of 159 appearances in three years. During that time he won both La Liga and the Copa del Rey."
Arsenal did not disclose how much they had paid to sign Ozil, but British media reports said the deal was worth £42.4 million ($66 million, 50 million euros).
"We are extremely pleased to have signed Mesut Ozil," said Arsenal manager Arsene Wenger.
"He is a great player, with proven quality at both club and international level. We have watched and admired him for some time as he has all the attributes I look for in an Arsenal player.
"I have said throughout the summer that we have been working hard to bring in top quality players to this football club.
"This has involved many many people across the club and I have always had the full support of the club in making decisions on the football side."
Ozil, who underwent a medical examination in Munich, told the Arsenal website: "I am thrilled to be joining a club of the stature of Arsenal and am looking forward to playing in the Premier League.
"It will be great for my own personal development as a player and I am particularly looking forward to working with ArsÃ¨ne Wenger.
"From our negotiations it is clear the club has huge ambition and I look forward to being part of an exciting future."
