Arsenal have reportedly completed the signing of Per Mertesacker.
French publication L'Equipe claims the 26-year-old centre back, rated in the region of £6 million, is set to join the Gunners two years after the club first showed an interest in the German international's services.
The Werder Bremen defender has only one-year left on his current deal at the Weserstadion, and is tipped to join Fenerbache left back Andre Santos in moving to Arsenal, with the Brazilian reportedly set to complete a €7 million switch to the Emirates later today.
Arsene Wenger has moved quickly to resolve his defensive issues at the Emirates following the weekend debacle at Old Trafford, with Armand Traore poised to leave Arsenal amidst speculation two others are set to join the north Londoners.
Wenger has previously highlighted the club's need to strengthen in midfield following the exits of Cesc Fabregas and Samir Nasri, and Yossi Benayoun is believed to be another Arsenal target as the Gunners look to bolster their ranks.
The Frenchman will have to work quickly with only two days left in the transfer window, but Arsenal are showing clear signals of intent in the market ahead of the 11pm deadline on Wednesday night.
