Both players enjoyed a successful season together in 2010-11 where they led Fenerbahce to the league title and also each player captained his national team in this past World Cup.
According to the Mirror and the DailyMail Arsenal will be hoping to sign at least one of them (Yobo and Lugano) especially after their latest injury that was sustained by Debuchy (torn ankle ligament).
Lugano and Yobo are both free agents as well, with Lugano's contract not being renewed by West Bromwich Albions and Yobo being released from Fenerbahce. And although the transfer window in England was closed on the first of September, Arsenal can still sign free agents.
