Arsenal have agreed a £42.4m (50m euros) deal with Real Madrid to sign Germany midfielder Mesut Ozil.
The 24-year-old has agreed personal terms but must undergo a medical before Arsenal can complete what would be a club record signing.
Ozil is on international duty and the medical will take place in Germany.
The Gunners have failed in high-profile attempts to sign Liverpool striker Luis Suarez and Gonzalo Higuain, another Real Madrid player, this summer.
But they are close to capturing Ozil after Gareth Bale's world-record £85.3m switch from Tottenham to Real t,riggered further deals on the final day of the transfer window.
Ozil joined Real from Werder Bremen three years ago for a fee believed to be about £12.4m and has played 155 times for the club.
