Arsenal scout Rowley tells Wenger to go for Werder Bremen defender Mertesacker

Germany World Cup star Per Mertesacker is in the sights of Arsenal.

The Daily Mail says Gunners boss Arsene Wenger needs to make at least two big-money signings, with both William Gallas and Mikael Silvestre departing. And if Sol Campbell joins Celtic it will leave Arsenal with just two senior central defenders, Thomas Vermaelen and Johan Djourou.

Mertesacker, 25, has been on the Gunners' radar for some time with chief scout Steve Rowley regularly making personal checks on him in action for club side Werder Bremen.

The giant defender's displays in helping Germany to the quarter-finals in South Africa have strengthened the view that he could do a job in the Premiership.
