The Gunners chased the Spaniard prior to signing Alexis Sanchez, but failed to convince the Catalan club to sell their man.
But with a series of injuries having hit his midfield and attack, Wenger is keen to push through a deal for the 27-year-old in the New Year.
And he may have a chance of doing so, with Pedro himself worried about his first-team prospects when Luis Suarez returns from his lengthy ban.
The Uruguayan – who cost £75m when signed from Liverpool – is expected to be given a prominent role in a front three alongside Lionel Messi and Neymar, which would see the current Camp Nou star ousted.
Pedro is likely to cost upwards of £25m and would bring Arsenal plenty of experience given that he’s won four La Liga titles, two Champions League, the 2010 World Cup and the 2012 European Championships.
