The Spain international has been one of the Catalans’ top performers over the course of the past few years, with his industrious playing style and eye for goal having kept him in the first-team alongside stars such as Lionel Messi and Neymar.
However, the addition of Luis Suarez and the change to Luis Enrique as manager has forced Pedro into more of a background role, limiting his playing time.
This is understood to have left the 27-year-old frustrated, with a move on the agenda for the end of the season.
Links with Liverpool have since emerged, but Arsenal are firmly in the battle and could match the £22m asking price Barca are said to have set.
Pedro is set to be a free agent in 2016, which makes a cash deal in the coming window attractive for the La Liga heavyweights.
