Arsene Wenger wants a new keeper to push current No.1 Wojciech Szczesny all the way next season.
The Gunners have been alerted to Ruddy’s potential availability ahead of next season and Sportsmail understands there is a strong willingness from the Emirates Stadium to pursue a move for the England international.
Reading goalkeeper Alex McCarthy has also been identified as a possible candidate to replace outgoing second choice keeper Lukasz Fabianski.
But Ruddy’s extensive top-flight experience puts him ahead of McCarthy.
Cardiff keeper David Marshall has also been watched, but his £15million price tag could prove a stumbling block towards a potential move to the north London.
